Well, we have the "ask" tab at the top. I don't see a need for a separate domain or anything like that.
I'm not sure what the solution would be exactly; the subdomain/forum idea is just a suggestion. If it was a separate forum, it could house all talk-related items and categorize them as "Questions", "Job Postings", etc.
I just wanted to see if anyone else had the same preference and if there are any better suggestions.
