Hi Maina, I have checked the social sites recommended by you. May be itis important to update on your article that Delicious no longer accepts bookmarks as it is now bought by Pinboard. Most of these social sites are being bought off and may discontinue their programs. May be you can even dedicate a new post for that. Otherwise, great piece of work there.
Every time you leave your account active on your computer those little Facebook linkis that are now at the bottom of most of the pages you go to report your browsing history back to Facebook. Who the hell do they think they are? I have never created a Facebook account yet through accounts of Friends I see my full name identified. Yes, I agree whole heatedly we need an alternative other then Facebook.
A 2014 Pew Research Center survey found that 91% of Americans "agree" or "strongly agree" that people have lost control over how personal information is collected and used by all kinds of entities. Some 80% of social media users said they were concerned about advertisers and businesses accessing the data they share on social media platforms, and 64% said the government should do more to regulate advertisers.
Snapchat is an image messaging application software product that was created by Reggie Brown, Evan Spiegel and Bobby Murphy when they were students at Stanford University. The app was officially released in September 2011, and within a short span of time they have grown immensely registering an average of 100 million daily active users as of May 2015. More than 18 percent of all social media users use Snapchat.
Instagram Stories have quickly outpaced the original Snapchat story. 11 out of 12 influencers now post more stories to Instagram than to Snapchat. It’s easy to see why: people watch 70% of Instagram stories with the volume on. Since the stories update average user time spent on Instagram has increased from 15 minutes to 28 minutes per day (Mediakix).
Tumblr is one of the most difficult to use social networking platforms, but it’s also one of the most interesting sites. The platform allows several different post formats, including quote posts, chat posts, video and photo posts as well as audio posts, so you are never limited in the type of content that you can share. Like Twitter, reblogging, which is more like retweeting, is quick and easy. The social networking website was founded by David Karp in February 2007 and currently hosts more than 200 million blogs.
According to the Pew Research Center, a majority of Americans at least occasionally receive news from social media.  Because of algorithms on social media which filter and display news content which are likely to match their users’ political preferences, a potential impact of receiving news from social media includes an increase in political polarization due to selective exposure.  Political polarization refers to when an individual's stance on a topic is more likely to be strictly defined by their identification with a specific political party or ideology than on other factors. Selective exposure occurs when an individual favors information which supports their beliefs and avoids information which conflicts with their beliefs. A study by Hayat and Samuel-Azran conducted during the 2016 U.S. presidential election observed an “echo chamber” effect of selective exposure among 27,811 Twitter users following the content of cable news shows.  The Twitter users observed in the study were found to have little interaction with users and content whose beliefs were different from their own, possibly heightening polarization effects.

Copyblogger published an interesting article several years ago, making the argument that blogs are indeed social media, despite the fact that people tend to put them in a category all on their own these days. In fact, blogs are one of the oldest forms of social media that dominated the web long before we were friending and following everyone on social networks.
Gen Z has an interest in privacy that subtly sets them apart. “Young people want to get away from the curtain-twitching village, where everyone knows everything about you,” Binns says. So while today’s teens spend a lot of time online, they don’t actually share that much personal information. And when they do share, it’s strategic. “You’re painting a picture of who you are and your image,” says Binns. “It’s your own shop window or brand.”
Some social media sites have potential for content posted there to spread virally over social networks. The term is an analogy to the concept of viral infections, which can spread rapidly from person to person. In a social media context, content or websites that are "viral" (or which "go viral") are those with a greater likelihood that users will reshare content posted (by another user) to their social network, leading to further sharing. In some cases, posts containing popular content or fast-breaking news have been rapidly shared and reshared by a huge number of users. Many social media sites provide a specific functionality to help users reshare content, such as Twitter's retweet button, Pinterest's pin function, Facebook's share option or Tumblr's reblog function. Businesses have a particular interest in viral marketing tactics because a viral campaign can achieve widespread advertising coverage (particularly if the viral reposting itself makes the news) for a fraction of the cost of a traditional marketing campaign, which typically uses printed materials, like newspapers, magazines, mailings, and billboards, and television and radio commercials. Nonprofit organizations and activists may have similar interests in posting content on social media sites with the aim of it going viral. A popular component and feature of Twitter is retweeting. Twitter allows other people to keep up with important events, stay connected with their peers, and can contribute in various ways throughout social media. When certain posts become popular, they start to get retweeted over and over again, becoming viral. Hashtags can be used in tweets, and can also be used to take count of how many people have used that hashtag.
