Congrats, Mark and the rest of the crew.
The phenomenal growth at FK speaks for itself. If it wasn't great, it would be so popular.
When I first joined and posted a site check in June, there were 6300 members. Even so, I had posted the same site check on three other sites - FK came through with about 8 replies in the first couple hours. I've been hanging around here ever since.
You've fostered an atmosphere that really achieves that sense of 'community' that is such a desirable trait for a website.
Kudos!
