So when I set the reward limit, is that a hard cap per person? They cannot adjust it and vote me USD 100 anyways? Or is it just a default setting to guide the voting?

As for the UI, it has rough edges, definitely. If D.Buzz can get the functionality right on all the features it has, I can wait for the rough edges to be smoothed out.

Agree! I've been using it as a 100% replacement for, or at least funnel into Twitter.
