Thanks for your comments! The idea of the conversation interface is that the user is driving the conversation. We wanted to make it extremely simple for the other person to see and respond. We don't have a good solution for the flip-side yet. It's one of the issues we found with certain translation applications that have user interfaces meant for two people. One person is probably not going to know how to use it.

I definitely do see value in this kind of interaction though, but we're going to have to be careful about how we implement it so we don't make the interface confusing for the person you actually want to communicate and not confuse!
