There was a great article I've never been able to find again about how the UI of Twitter naturally guides users into de facto bullying, and most of the advice given by experienced Twitter users (e.g. check existing replies to a tweet before adding your own) is working around UI choices made by the system itself.
I wonder how many of those bully-inducing UI features are also present in software like Mastodon or Diaspora, and are therefore disasters-in-waiting, to be triggered once critical mass of users is reached.
