That's interesting Michael.
What I would think would be good would be for something to integrate with VB
the same way that PP and the rest of the software here does - install it and you're just about good to go with the regular header and footer.
If posts to a blog were very similar to the forums, each user could do his/her own thing.
I'm no software developer but I'm guessing that the elements are already in place in most of the software here to be able to develop that and I think that it could be a giant draw for forum/community sites.
