You may well have found this article through Facebook. An algorithm programmed by one of the world's biggest companies now partially controls what news reaches 1.8 billion people. And this algorithm has come under attack for censorship, political bias and for creating bubbles that prevent people from encountering ideas they don't already agree with.

Now a new kind of social network is emerging that has no centralised control like Facebook does. It's based on blockchain, the technology behind Bitcoin and other cryptocurrencies, and promises a more democratic and secure way to share content. But a closer look at how these networks operate suggests they could be far less empowering than they first appear.

Blockchain has received an enormous amount of hype thanks to its use in online-only cryptocurrencies. It is essentially a ledger or a database where information is stored in "blocks" that are linked historically to form a chain, saved on every computer that uses it. What is revolutionary about it is that this ledger is built using cryptography by a network of users rather than a central authority such as a bank or government.

Every computer in the network has access to all the blocks and the information they contain, making the blockchain system more transparent, accurate and also robust since it does not have a single point of failure. The absence of a central authority controlling blockchain means it can be used to create more democratic organisations owned and controlled by their users. Very importantly, it also enables the use of smart contracts for payments. These are codes that automatically implement and execute the terms of a legal contract.

Industry and governments are developing other uses for blockchain aside from digital currencies, from streamlining back office functions to managing health data. One of the most recent ideas is to use blockchain to create alternative social networks that avoid many of the problems the likes of Facebook are sometimes criticised for, such as censorship, privacy, manipulating what content users see and exploiting those users.

Most of these services are in pilot stages but one, Steemit, has been successfully operating for a number of months and its user numbers have grown significantly. Its main function is as a content-sharing site where posts are ranked by popularity, similar to Reddit, although it has recently added a private messaging function and the ability to follow specific users.

Perhaps its most important feature is the way users are rewarded. Every time they produce or share content, they receive Steem tokens, which are like shares in the organisation. These can be exchanged for any real-world currency or used to vote on how the platform will develop, giving users governance power.

Steemit doesn't control or own user data since it is stored using blockchain and so it doesn't sell the data to third parties such as advertisers. Being built on publicly available and visible blockchain technology prevents any form of censorship and discrimination in the system. The network doesn't filter what content users see with an algorithm posts are ranked by pure popularity and there is no central entity that can manipulate or censor the data, or be forced to by governments.

How decentralised?

Most of the other decentralised blockchain social networks are very similar. There is Synereo, which has the added option to post images and hashtag content, and Akasha, which is like a decentralised Twitter, as well as ThanksCoin and Yours Network.

For all their interesting ideas, however, social networks built on blockchain face some big questions over whether they can really achieve what they promise. To begin with, most are funded by venture capital or individual investors and don't have clear business models for generating sustainable revenue or profits.

There is also the problem that using blockchain as the underlying technology means any content shared becomes a matter of public record. Data and, more importantly, users' history cannot be erased or changed, which means a slight mistake could haunt people forever.

But there is also some doubt over whether these projects really create decentralised social networks at all. They must entail a certain degree of centralisation to develop the code behind them and solve problems such as software bugs or potential hacks. They have been set up by a small group of people that have decided to use technology in a certain way. Some projects might involve users in a more democratic way, but blockchain does not remove centralisation and politics altogether.

What's more, Steemit looks much more like a blogging platform than a social network as we know it, and so far has a very limited range of user-generated content. To become viable alternatives to the likes of Facebook, blockchain networks will have to find a way to attract a much wider population. One strong appeal might be that they provide users with a way to make money from their work rather than allowing someone else to exploit it.

Unequal power share

Yet there's a limit to the degree to which Blockchain networks are really empowering users. They do not offer alternative economic models, such as collaboration between a community. Instead, they just offer a way to be a part of the "market/attention economy", where individuals receive money for clicks and likes.

And on a political level, while Steemit offers users the chance to gain power, it doesn't distribute it equally. The more popular the content you post or like is, the more power you have. Not only does that lead to inequality, but it also might have distorting and negative effects on the content. For example, it could encourage users to post more dumbed-down, salacious or even fake content in pursuit of the highest readership something that is already a problem for social networks that don't pay users for clicks.

Blockchain does offer a technological solution for creating alternative organisational models. But it's worth remembering that decentralisation has been behind the internet's architecture since its inception and it has not led to a significant redistribution of power to the general population. That said, blockchain networks are still in their early stages, and their focus on developing more egalitarian models for social networking means it is worth watching how they develop.

Facebook Follows Snapchat, Instagram With its Own Version of Stories – PCMag India

Facebooklike Snapchat and Instagram before itis getting an ephemeral, video-based Stories feature.

The social network is testing Stories in Ireland, where as of today members can use the new format to share videos and photos with their friends that will disappear after 24 hours and won't automatically show up in their News Feeds.

The idea is that people will use their Facebook iOS or Android app to add photos and videos from their smartphone throughout the day, and their friends will tap through the stories to see what they've been up to. It's an opt-in approach, although if you want to make your story harder for people to ignore, you can set it to show up in people's News Feeds.

There will be camera effects, too, like masks and frames that you can add to videos and photos. Your friends can reply to or comment on your stories with a new accompanying feature called Direct, which is essentially a chat room. Like Stories, it is separate from the News Feed that makes up Facebook's bread and butter.

If the stories concept sounds familiar, that's because it is: Snapchat pioneered it nearly four years ago with its own Stories feature, and Facebook-owned Instagram copied it last summer. It's hardly surprising, then, that it would eventually show up on the world's largest social network, which described it as an evolution of how people share their lives online.

"The way people share today is different to five or even two years ago it's much more visual, with more photos and videos than ever before," a Facebook spokesperson said in a statement. "We want to make it fast and fun for people to share creative and expressive photos and videos with whoever they want, whenever they want."

For now, Facebook Stories is only available in Ireland, which has also served as a testing ground for some of the company's other recent projects, including a beta version of Direct. Facebook said that Stories will arrive in additional countries "in the coming months," along with some other new camera-related features.

Also today, Facebook overhauled how its Trending stories section displays, promising to show everyone the same items.

Facebook Overhauls Trending, Will Show Same Topics to Everyone – PCMag India

Facebook will no longer personalize the list of trending topics it displays to users.

In a Wednesday blog post, the social network said that everyone will now see the same stories in the Trending section, regardless of location. Facebook is making this change "to help make sure people don't miss important topics being discussed on Facebook that might not show up in their News Feed," VP of Product Management Will Cathcart wrote.

Facebook is also rolling out "an improved system to determine what is trending," Cathcart wrote. And finally, trending topics will now feature a publisher headline below each category.

The company's algorithms will determine what's trending by looking at the number of publishers that are posting articles on Facebook about the same topic and engagement around that group of articles. In the past, topics might have trended due to high engagement around a single post or article.

This new method "should surface trending topics quicker, be more effective at capturing a broader range of news and events from around the world and also help ensure that trending topics reflect real world events being covered by multiple news outlets," Cathcart wrote.

For the uninitiated, Facebook's Trending section shows you popular topics being discussed on the service. In the latest version, you'll see a news headline under the name of the topic to give you more insight about why it's trending, a highly requested feature.

"The headline that appears is automatically selected based on a combination of factors including the engagement around the article on Facebook, the engagement around the publisher overall, and whether other articles are linking to it," Cathcart wrote. Previously, Facebook used the space under each topic to display the number of people talking about it.

Like before, you can click on any of the topics to see additional sources and posts about it.

The changes are rolling out now and should reach everyone in the US in the "coming weeks," Cathcart wrote.

Initially, Facebook had a team of human curators who selected topics that appeared in the Trending box. Amidst reports that the team favored liberal news outlets and supressed conservative voices, Facebook in August ditched human editors for algorithms. But that created another problem: fake news. The social network has pledged to crack down on that, too, with reporting tools it rolled out in December.

Swipe right: Penn’s new social networking app – The Daily Pennsylvanian

Photo: Blake Engelhard / The Daily Pennsylvanian

2015 Wharton graduate Blake Engelhard aims to use "swipe culture"to create valuableconnections and friendships throughNecter, a new social networking app.

The app is a connection/introduction app, College senior Olga Belyanina said, who is in charge of business development, so connections are made through mutual friends.

These mutual friends are the key to how the app works. The app gives users three categories to choose from: work, dating, and friendship. Friends can introduce mutual friends looking for the same thing whether that be someone to go to the gym with, a formal date, or just a study buddy.

Really what we see is creating a movement around being open about what youre looking for and helping others find the things that they need, Engelhard said.

Engelhard first gotthe idea for the app in January 2016 when he wastraveling for a consulting job.

Moving from city to city its really hard to meet new people, Belyaninasaid. [This is] a platform where you could meet people with a purpose.

The company is building off the recent success of companionship apps, which have tripled in the last two years, according to research from theDating Apocalypse.

The swipe culture and the swipe way of life is a way of connecting, Peter Groverman, an advisor to the company said. People are getting more and more connected every day that passes.

Groverman has been a part of focus groups that have helped develop different components of the app.

Its really easy to use, its very intuitive, Groverman said. You can navigate it with complete ease.

This ease of use didnt happen overnight. For the past year, Engelhard has worked to assemble a team to make his idea a reality.

Penn hasbeen an unbelievable resource in terms of having students come into the office and do focus groups and test the prototypes and things like that, Engelhard said.

The result is an app based on connections made by mutual friends, which Engelhard described as like Tinder, but less creepy, a little less weird.

Belyaninasaid something similar:In Penns environment we kind of find our little niches, we have our little bubble, she said. This will make it possible to build a community and raise awareness about whats going on in other areas.

Penn is the first campus the app is launching with, and it was officially released on theApp Store on Monday.

Necter is hosting a launch event at Allegros Pizza on Thursday from 10 pm to 1 am and plans to turn Penns late night pizza place into a club, complete with a band, a DJ and freebeer and pizza.

Groverman feels optimistic about the app's potential.

[Venmo] started in a dorm room and then boom it exploded and became such a phenom, Groverman said. This has all the hallmarks of that.
