Yup, too bad they only update once a month. I find that the authors of the articles there typically have more frequent updates on their personal sites. I would also recommend the following:
http://meyerweb.com/ - Category: Web Design (CSS Layout)
http://www.positioniseverything.net/ - Category: Web Design (compatability)
http://www.456bereastreet.com/ - Category: Web Standards
http://simplebits.com/publications/articles/ - Category: Web Design (has articles on ALA and his own site), also check out dans "friends and colleagues section under "notebook" for other great links.
