I just thought I'd point out a great ASP.NET site I discovered about a month or so ago:
It's the first ASP.NET site out there that I've ever seen to focus mainly on web standards. There's lots of good commentary from the site author, Milan Negovan, on issues related to programming with web standards in mind. He writes practical articles describing how to make good standards based sites using the .NET framework (even though some parts of the framework tend to generate non-compliant markup). I always look forward to his articles, and think it's great to see somebody tackling these issues head on. Go check it out.
