I use ZD, Twitch, Discord, and Skype as far as social media goes. I'm not as active on ZD as I once was but I still try to log in at least every other day to make a few posts. On Twitch, I tend to watch a few people usually for a few hours at night when I have some time. Discord I barely use because I hate the interface. I mostly use it to talk to some people. Skype is pretty dead after most people moved to Discord but I still use it to talk to DARK MASTER and athenian200. So I'd say social media is of moderate importance to me.
Ignoring instant messenger aspects, e.g. Facebook Messenger, then I don't use the majority of social media apps. I use Reddit a lot, particularly for sports, games, hobbies, etc. Also generally follow memes and subreddits with content I find humourous. I think that hobby based subreddits are the best ones are they are places that can help give good advice, nuture good discussion if properly moderated and help grow those respective hobbies communities. I try to avoid partaking in subs such as political ones as I think this aspect in particular is the worst of what social media can offer.
I have Facebook but also avoid using for similar reasons to avoiding political subreddits it. They're propaganda machines and rarely foster a good discussion environment. I also think Facebook, Instagram and the likes have a negative affect on how people view themselves, everything becomes a comparison to other people despite the fact that the majority of people will only show the best parts of their lives which makes them look artificially better than they are. On top of that, they're genuinely very poor at moderating their user base and you end up with problems like rampant pedophilia, scientific and political disinformation and vitriol (Twitter is horrendous for vitriol towards sports stars who have had a bad game).
I don't really use social media. Discord and forums are pretty much the closest i get and ngl i prefer that. It's more like real-time chatting and having fun with a group of online friends than social media will ever be.
