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. 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. 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.
