Like the changes to the main site, the forum upgrade is pretty major. The difference is that you won't see as much of the 'major-ness' in the forum upgrade because it is also internal. vBulletin re-wrote how they do layout and such. The change of philosphy of "tables bad...., CSS good" is applied. In older versiosn of vBulletin, everything is structured with tables. that's not so much the ase with the newest versions. That change along is pretty big.
So yes, hopefully some quirks will go away, but I imagine we'll have a whole new set of them to drive us batty!
As a note, QuinStreet has over 20 forums all in vBulletin, so if there are quirks, we'll see them.... If not here, then on some of the others like VBForums.com or forums.codeguru.com (which are a couple of our bigger ones).
But alas - it is progress, which we've needed here for quite a while!
