Twitter is awesome, I have two accounts.
One for the few people I know IRL that are on it, but I also follow cool people in certain industries, some funny people, and I've met some ppl thru tweeting at big accounts. My other one is for anime/art that I like.
There's a huge welcoming community on twitter for niche topics. You have to just keep at it for a bit, and you'll end up with an awesome feed following seriously funny people, content creators, speculators, etc.
For example I have a twitter bubble for Dragon Ball, and I get the fastest info from twitter, the best art, friends I've met online, and even access to DBS staff!
Obviously there's the deep dark side of twitter, but it's very easy to ignore.
Twitter is probably the best social media.
