If there are going to be sub-forums of the Lounge I recommend having one for newer Macs and Apple components, one for PC and other computers and operating systems (which could include video game consoles), one for automobiles (since there seem to be a lot of car threads), and one for everything else.

The sub-forums would include a broad range of items (for example, the newer Mac forum would have discussions about hardware, OS X, iPods, iPhones, OS X software, etc). It would keep the "anything goes" element of the lounge to some extent but would also organize some of the content in a logical manner.
