I don't know if I can give a completely accurate answer, but I think my fave is Twitter. I don't have a personal account (one I attach my real name to) at the moment, but I did in 2009 before it got really popular; I deleted it because no one was using it. I love the idea of being able to post whatever's on my mind without worrying about flooding people's feeds, but I'm scared of being a flop with no followers. (I just started using Instagram and I'm struggling to hit 100 followers, so you see my fear.)
