I've noticed that most of the web forums I visit often are "powered by Vbulletin". There are forums that I visit, but not very often, such as pencils.com, mysears.com,abebooks.com. These are not Vbulletin powered sites and they seem very haphazard and jumbled. I don't know how things look from the administators point of view, but from the users point of view, Vbulletin is a superior product.
