Good thread, exactly what I would have posted *g*. I am currently building our mainsite for a online graphical/digital painting community. I need vB to be integrated in the mainsite for displaying the news, articles and everything else like polls, authors, tutorials and more. I have done a big research on every cms that could handle vB as integration.
I think I give wordpress a go along with the bridge for vB. The main reason I choose this is that wp allows you to display a thread as a newspost on the frontend and all comments belong to this posting will be done in the forums as discussion
I didn't spent that much hours to have a look how drupal handles all this. But for me wordpress is way easier to modify my template than drupal does.
Bad thing about vbAdvanced is the lack of 3rd party programmers who could do a paid job to get my style working along with this
