I agree that the style is similar to SitePoint. (Perhaps the header, but not the forums themselves at all.) However, there are also many other sites on the 'net with the same style. The color combination is actually very popular. In fact, I actually originally picked out the light blue / dark blue / grey colors from
http://www.phpbbhacks.com/forums/ in addition to
http://www.overture.com and the Overture blue/lighter blue logo. Later I chose the orange after seeing it against blue at
http://www.coolhomepages.com - it's also at
http://www.ipodlounge.com in addition to quite a few other sites where it's against the same shade of blue.
As for the large number of forums. I agree there are a lot. However, they're all pretty populated with the exception of our ColdFusion forum. It's not like we have 40 forums with 10 posts dispersed among them. Rather, we're a growing community with almost 3,000 members. Check out
http://www.dbforums.com and look at how many they have!
However, I definitely thank you for your feedback. I'm always tinkering and toying with one style element or another. (It was torturous murder not being able to alter the style during the month of voting for vB board of the month - but well worth it in the end!) Therfore, I'm completely open to construtive criticism.
