<20 here. I'll go down the list: Facebook is stupid. I have a profile because I've always had one, and it's occasionally useful for groups and events. But most of the time that's where my mom hangs out and the volume of posts is way too large to sift through. And all the notifications get annoying. I use Instagram more often than Facebook, still not that often. Mostly I follow musicians and funny people (also marniethedog because yes), and every once in a while I post weird pictures of myself or the stuff I'm doing. It's cool, I guess. I tweet more often than I read my Twitter feed. Same issue as Facebook: there's too much fucking content, and no good way to sort through. But like every couple days I'll read a couple tweets and chuckle at one, so I still have a profile. It's also useful for scratching the itch to say stupid shit to someone without annoying the heck out of my family/friends. I don't really understand Snapchat? I have one, but rarely use it, and mostly only to reply to people, because seriously what the hell kind of pictures am I supposed to send? It eludes me. I used to have a Tumblr. I downloaded Yik Yak about a week ago, it's pretty lame, mostly because of where I live. I use it pretty much as if it was anonymous, less interactive Twitter. I'm not going to participate in the author's weird Medium hype. So that's my view.
