The metrics I quoted may not be precise, but they are still representative. How many more subs does android have on your instance compared to askandroid?
That aside: Just look at the post & engagement numbers!
My argument is that, at the moment, the community is too small for so many specific sub-communitites. And this approach sends users into oblivion.
Most of the deleted questions aren’t even reposted in the other sub, and if they are get way less responses.
