This is a pretty cool site: www.goodfuckingdesignadvice.com
I can't remember how I came across this site but since then, it's been a great place to check out other great design sites. To add a little humour to the site, there is a 'Family Friendly' button that puts a strike through the word 'Fuck' to ensure appropriateness. Tying in design jokes and humour, the site becomes a great laugh. I've downloaded a few of their wallpapers for my own use.
