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. 
The picture here is a bit different if we look at the brand names. WhatsApp and Messenger are in a close race for the top spot. But both of these most popular social media apps are owned by Facebook so the competition may not be as fierce as between completely separate companies. Then there’s a lot of Asian apps and then on the sixth spot is Instagram, again owned by Facebook.
UK researchers used a dataset of more than 800 million Twitter messages to evaluate how collective mood changes over the course of 24 hours and across the seasons. The research team collected 800 million anonymous Tweets from 33,576 time points over four years, to examine anger and sadness and compare them with fatigue. The "research revealed strong circadian patterns for both positive and negative moods. The profiles of anger and fatigue were found remarkably stable across the seasons or between the weekdays/weekend." The "positive emotions and sadness showed more variability in response to these changing conditions and higher levels of interaction with the onset of sunlight exposure." 
Social media is not something you can simply "tack on" to the rest of your marketing, branding, PR, and advertising efforts; it needs to be a fully integrated part of the mix. In doing so, you can create a cohesive and scalable experience for your customers. Think of it as a means to an end, and not an end in itself. Also, it's not as hard as it sounds.

Younger generations are becoming more involved in politics due to the increase of political news posted on social media. Due to the heavier use of social media among younger generations, they are exposed to politics more frequently, and in a way that is integrated into their online social lives. Social media was influential in the widespread attention given to the revolutionary outbreaks in the Middle East and North Africa during 2011. During the Tunisian revolution in 2011, people used Facebook to organize meetings and protests. However, there is debate about the extent to which social media facilitated this kind of change.
Isabelle agrees. “Constant screen time damages your ability to see, and it also causes internal damage, such as anxiety.” Studies have shown that social media use can negatively affect mental wellbeing, and adolescents are particularly susceptible: one nationally representative survey of US 13- to 18-year-olds linked heavier social media use to depression and suicide, particularly in girls. And 41% of the Gen Z teens surveyed by Hill Holliday reported that social media made them feel anxious, sad or depressed.
