I was wondering on this idea - perhaps this has been discussed before. It happens often to me that I have some question to ask and I think:
I'd like to ask this on SE, but I don't know if there is a proper site for this kind of question - or if there should be. It would be nice that SE had a site for asking this meta-question : where does this question fit?
Questions on this hypothetical SE site would be either forwared to the proper SE site (perhaps in beta or proposal state), or closed (or answered?) as "this does not belong here". Perhaps even concrete answers to the "inner" question could be allowed (I'm not sure). Also, this could be useful to get ideas for new SE sites.
BTW: I'm not sure if this question belongs here :-)
