overhear.us is extremely experimental at this point and could change dramatically. we spent 6 weeks and made it on a whim and it has already proved useful as a feedback device internal to YC.
there remain a lot of obvious improvements to be made product, but it is an experiment. right now we are eyeing it and seeing how people are using it, and how we can get them to use it better.
i'd love to talk more about it, but i have a feeling i'm already being pulled in to an online war by responding to this comment.
