I looked at the "www.xpthemes.com" and I have to say

. It looks crappy. The posts do not have descriptions or anything. I am glad the ratings are not there but where are the comments?
The site basically, just looks like it is a test site. I can see it being more XP like in the future using some scripts and stuff (like a start menu dropdown and a start bar of sorts).
It seems though, that the site is not too offensive and plain enough that someone would not be too mad if their work would be on it. (it is not p0rn or selling stuff out of the ordinary) The work does get more exposure and explains why people get high downloads or downloads days after uploading.
The site is also much faster and doesn't have all the add ons like message boards, upload areas, account junk, you know the stuff we love and can't do without here; But there it would be a burden.
Well, I think it is a good idea, though I wonder why that could not be impleneted here. Then again names are important and xpthemes probably goes over better than wincustomize.
You know I always thought Micro$oft owned that site.
