And all that can't be done with vBulletin, as vBulletin has fixed set of features and style only shows what vBulletin tells it to show, just like any other forum system. Designer can move buttons across the page to make navigation easier, but that's all, and it doesn't make forum more useful - it just makes forum slightly more useful, so it doesn't magically turn design to web 2.0. Style designer can't add new features. So in this matter "web 2.0" term can't be applied to vBulletin styles.

Then all "web 2.0" styles designed for vBulletin are quite opposite to what they claim, as they use lots of gradient images increasing page size compared to default vBulletin style, and styles that do reduce size are different from default style by so little that it doesn't make them 2.0. The only way to make it smaller is to use divs so code would be as tiny as possible, which would require complete rewrite of all templates, which brings me to point about 2.0 styles being semantically correct.
