I believe at least some people here have some stuff they want to do that is not orthogonal with rationality and may be helped by a group effort. Translation of some materials, writing articles, research, programming projects, just discussions of some topics. Then there is going to be a Group Bragging thread, where people can tell how much they have managed to do in a month or so. If the group hasn't bragged for a few months, it's considered dead. That can also give us some new info about group building and maintainance, which seems like a neglected topic here, as well as some data about which groups survive better than the others.
