I like it, but how does this solve the thing that I thought was the reason standups exist: to find out who needs help and to verify that the priorities are still right? I see how this can be used for status reporting, but who really cares about that? Note, I'm not trying to HN-diss this tool. I really want this tool - assuming it helps us actually use the standup for setting priorities and helping each other out.
