In all the excitement, we forgot to ask about the API. I am curious what they will provide, and with what limits. One big problem I had with bit.ly on Twitter is there was no way to get all shortened URLs pointing to a "real" URL. This was a problem because I wanted to search for references to the "real" URL. The lack of that feature of course empowered dedicated services like backtype (I suppose), who have special deals with Twitter so that they can get all references.
