Stack Overflow works so well because it has users from loads of different programming languages. By merging the Blender proposal with the CG Artists proposal, we can get more experts and more momentum. It seems that Blender would be a great tag for the CG site.
Shall we merge proposals?
Although I accepted MidnightLightning's answer, I really like AbrahamVanHelpsing's answer as well. Please read both answers and vote on the one that you think is the best course of action.
It seems that the majority is now predominantly for Blender as its own site (myself included). Unless there's another shift, I'm going to accept AbrahamVanHelpsing's answer
