I recently discovered http://agileshout.com, a Stack Overflow implementation focused on questions about Agile.
The site has fairly low traffic, it seems, but it also seems very new. I'm wondering what the value of a topic-specific Stack Overflow-like site offers. Why would I go to that site instead of looking at the questions with the agile tag on SO?
The broader question is — what value do topic-specific Stack Overflow sites have? I could see it within a company firewall, but not for public use.
