Wow - I should bookmark this thread in case I ever have delusions of wanting to start a forum :)
I noticed it, felt slightly amused (a "was that there before?" feeling), and clicked on recent posts. Besides craigslist - there aren't many quality sites with significantly less graphical clutter than WebmasterWorld. You can't blame a webmaster for tinkering, but then again I guess you can't expect that the however many tons of other webmasters that visit will think it is a good idea.
I think for April fools day Brett should use a facebook like skin with pure Ajax & Flash combo.
