This is completely irrelevant. Sure, non-internet-savvy people may just go to bbpress.com, but as you mentioned, anyone who has the faintest knowledge of the 'net will google it at least.

If you simply type "bbpress.com" into a browser in hopes of finding it, then you're almost definitely not going to own a server to run bbPress on anyway. If bbPress was aimed at beginners, I'd agree, but it's not; it's aimed at site administrators.
