Usability web sites du jour
The National Cancer Institute's Usability site is a great reference. I especially like the way they try to sort through the clutter of sometimes conflicting usability guidelines available by assessing the amount and types of evidence to support specific guidelines.

Also, what's up with our buddy Keith over at UsableWeb? Looks like he's been too busy with the new day job at IBM to do much updating. He even calls it a "stale" site himself . I'll have to pester him about it at CHI. ...but if your just starting out, there's no better place to immerse yourself to learn about usability as it relates to the web.
