I adore Twitter. Absolutely love it for several reasons.
It's incredibly useful. I follow several Twitch streamers and podcasts on Twitter, and it lets me know when they're streaming or when a new episode is released almost instantly. Ditto for youtubers that make series' of lets plays. For a while youtube's sub box was completely broken and wouldn't notify me of new uploads, so I'd miss them when I was looking for something to watch.
It's fun to follow certain things like Food Porn or Emergency Kittens. It's also fun to follow certain personalities of media you like. But that can also be a problem. After reading all the toxic crap coming from MovieBob I unfollowed him. The 140 character limit really reduces the content that can be delivered. So it can tend to descend into...
1) "witty" comments about [insert issue]
2) Passive aggressive snark
3) Smug condescension
4) Poor attempts at comedy
So basically it's The Escapist forums.
Twitter offers a lot for how simple it is. You pretty much control your experience by who you choose to follow. The block feature and mute feature are great tools for cleaning up your feed. It's just what you make it. Twitter isn't a place for debate or civil discourse, it's just another thing that can, has, and will continue to be misused by several people. But from what I've experienced, it offers a better way to tune out the bullshit than almost anything else. I'm oblivious to nearly everything on Twitter if I choose to ignore hashtags. And if the site's changes got you down, there's always tweetdeck. I enjoy it a lot better than facebook, which lost it's appeal after I left university. I guess the way I can control what appears in my feed is really appealing.
