I’m pretty happy with what I’ve managed to do with the bbpress installation on my site, rockstarwire.net/community
I have even released a plugin of my own, bbPress Advanced Statistics, which essentially adds a shortcode that displays a phpbb / vBulletin-esque “who’s online & statistics” section, you can see an example on the bottom of my site or you can check out the screenshots.
I’m optimistic about the future of bbPress, I just wish my community actually used the forum after all the work I’ve put into it!
