FAQ: "Why is there no retweet button?" Let me answer. The key here is to create a structure that makes everyone feel safe enough yet provide enough ways to explore. The "retweet" button is the root of all evil because it makes it trivial to share people's comments out of context and turns everything on Twitter into a performance art rather than a conversation. It's impossible to have genuine conversation in that environment because you're engaging in conversations to win in a public performance duel, instead of actually communicating. That said, I do think there are various other ways to add more discoverability of conversations. Feel free to add your thoughts.
