I think as a community, we're in a bit of a tight spot with regard to Stack Exchange. If we don't redirect users to this site from the existing support forums, we'll never meet the daily site visit requirements to exit beta. However, there's still a possibility that we make this the primary support form and we'll still be shut down. If that also meant the data on this site would be lost, that would be a huge blow.
So what happens to the data if we're shut down? I know it's liberally licensed - is there a way to migrate it to SE clone software? What about valuable metadata, like user reputations, tags, etc.?
