I disagree. Instagram, yes, as it's pretty much a facebook addon these days, but: - Twitter is generally a way for people to follow famous/semi-famous people nowadays. Most people don't go there for their friends. If they follow someone, it's because they WANT to see what they have to see. There is little pressure to 'follow' someone back, like there is with Facebook friends. - Reddit is semi-anonymous. The running joke is that you never want anyone in real life to know your reddit username. It's all about sharing, but it does not have the same kind of "dredge up the past" issue. - HN falls in with Reddit. I know few people who use HN, and those that do I don't communicate with on it. Hell, most people don't even pay attention to usernames unless it's someone well known like tptacek.
