I do. It's great.
Some people like to think about sites like Facebook that's just a way to measure e-dicks or to mind some Mr nobody's business. That behavior, compared to a forum, it's like an user spamming his own blog or attempting to be Mr funny guy for a few more likes or stalking someone's profile because their avatar remind you something you like. Sure, it happens a lot, but it's not what's all to it.
For example: I use Facebook to draw an imaginary closeness with some people that could never be reached in real life, because of time restraints or the distance. I can also see what other stuff people shared (yes, most of it is shit, but if you spend two months hiding all the dank meme groups you end up with interesting stuff) and keep myself updated to stuff I'm interested in from more famous people (like singers). I also use YouTube comments to find uncredited song names (believe me, it happens all the time), forums to see or share thoughtful opinions and so on. I used to be on Reddit until it became too shitty for my tastes.
Truth is, people like to complain a lot about popular stuff, as somehow it makes them feel special. Those you often see complain about social media are on sites like reddit or 4chan all the time. Those who often complain about football watch shitty esport teams (which, by the way, are hundreds of times more likely to partake in fixed matches). Those who complain about gossip media follow blogs of their female Asian idol, and so on.
Bottomline: use the instruments you are given in a way you feel productive. Don't need it? Don't use it.
