There are millions of people out there wasting their time on Facebook every day while they should really be posting on Xenforo boards. So, how could this situation be improved? Well, what if there was a sort of Xenforo site similar to Facebook? Where all Xenforo boards (or a subset of them) participated. Users could choose to use global usernames, or local usernames valid only on specific boards. (I think Wikipedia does something like this for different language versions of their encyclopaedia.) I suppose participating boards ought to have the same or very similar rules & terms. A user could join a new board as easily as FB users join new groups. And there would be a search feature for finding boards to join according to their area(s) of focus.
The technical side of this idea is probably where it all breaks. No idea how it would work, really
Mostly I'm just curious if others have had similar ideas, or if anything like this exists out there, why it was a success or failure etc.
