I guess this falls into a feature request of sorts as much as it is a question. I was looking over some other Stack Exchange site and discovered 3d modeling software.... I thought, "this would be a good question on Super User." One thought led to another and before you know, I thought, "I wonder if there is a way to cross-reference this question on Super User?"
Is it possible to allow other Stack Exchange sites to enlist in a cooperative that allows for questions to be referenced? I see some value in even migrating questions. The mechanics of such a feature would be phenomenal, I think - but certainly do-able.
The benefits of cross-marketing the sites includes:
- increase size of audience
- increase site exposure & visibility
One immediate problem I see is population of tags. It may be that instead of a full migration to SOFU, instead a header could be displayed that links to the originating site.
