Like you said.. What sets the site apart is the community.
It may or may not happen if you set up another 'Monks' site, but, just perhaps it will happen..
I stayed with Perl Monks, because it fit comfortably. I don't go so much to other places, because.. They just don't feel as welcoming.. The atmosphere just isn't there.
And, as the old addages go: "You only regret the things you never do" and "You never know unless you try".
Personally, I think it'd be a great idea to have many monasteries.
