bbPress 2.x, the new plugin version, is an awesome WordPress plugin! It's very well developed, modular and extendable and so is a role-model for other bbPress and WordPress developers and the whole community! Have a look on the clean and well-documented code which is not to be found that often in the WordPress community (sadly!) and you know what I am saying.
As for the features you maybe want more of them after first sight but if you think twice, you'll see that bbPress has absolutely no overbloat and just plain works! It fully breathes some "minimalistic" approach to forum software but really has a powerful core! Just have look at all the bbPress extension plugins already out there and you'll see what could be done on top of this foundation.
I really like bbPress 2.x! And seeing new support forums and other kind of forums pop up every week powered by it just proves that it is top notch and will have a great future! The bbPress community is already growing around the world and getting stronger every day!
