I think Twitter is especially bad in comparison to other sites because it incentivizes people to post their real names, photos of themselves, etc. Even worse for this issue is the ability to retweet, and the trending page of Twitter. Instagram for comparison doesn't have this problem to the same extent because it's about sharing photos and not about following every new trend. This design gives those that live their lives as online reactionaries a 24/7 outrage factory. The trending page is a constant line of pitchforks and threads to bring them to. Regardless of the benefits of the service I think it's hard to deny how the site's design contributes to the problem, at least to some degree.
