Referring to things like Facebook, Twitter, and similar: I do not use social media. I do not find social media to be meaningful.
Social media as I understand it is based on "microblogging", i.e. short posts about a person's life, thoughts, etc. Sharing random fun facts about life is fine, but it's really suboptimal for thoughts, especially political ones. Social media is usually designed in a quick "consumption"-oriented style, often leading to flamewars instead of in-depth discussions because of its "quick" and "short" nature. Modern social media recommends new posts and people to people based on what they "like" and "boost" further creating an information cocoon, "shielding" them from new ideas, rather than allowing for natural human distribution of good articles.
Instead, I read and write articles and share those that impress me naturally.
Most popular social media services such as facebook are also nonfree and have extra problems.
Sharing some fun facts about life is okay. I do that too. Just don't use microblogging for should-be-extensive topics and don't use these "posts feed" things.
