Proposal: Game of Go
We already had several discussions on merging game-of-go and similar proposals into boardgames.SE.
Those who opposed the merger mainly argued that a go player sees himself as a go player, and not as a boardgame player that happens to play go. So they want a separate site to identify with.
On the other hand there are activity concerns. boardgames.SE isn't overly active, and I assume game-of-go won't be super active either.
The new virtual subsite feature seems ideal to address both of these concerns at the same time. Go players get their own site with separate reputation to identify with, and boardgame.SE gets the activity.
One thing that's still required in both cases are go specific markup extensions.
