Get rid of censorship. They had a good idea with live streaming video and whatnot, but they're beat to everything by Instagram and Snapchat.

As it stands now, I deleted Twitter simply because it's nothing but corporate accounts, overly aggressive SJWs posturing over every damn thing, and the only content I actually cared about was reposted from Instagram (apart from a few people I know who live streamed, but have since switched platforms). So now I only use Instagram.
