You might want to see perlmonks from different lights, which I rate very high. How many times user get satisfactory answers for that question ? What encouragement and directions users get from the site etc.. For me, personally, 2660 (logins in last 30 days) is a sound number, who want to help me with Perl. Community is, and should be for the user, and considering that aspect, Perlmonks has higher value compared to other site IMHO, regardless of stats you mentioned.
