Below are some of my favorite blogs on web design... if there are any additional ones you like, send me the link and a short description of why you like it, I'll add it to the list.

A List Apart
Good articles on web design techniques, written by top people in the business.

Eric Meyer
Eric is Mr. CSS. His blog is a mix of personal and web design, but his web site has a lot of resources for designers.

Josh Porter
An employee of User Interface Engineering, Josh is one of the best thinkers I've come across on what's happening on the web. This is his own blog (he also contributes to UIE's Brain Sparks, listed below), in which he writes extensively on what's happening online today and what may be coming down the road.

456 Berea Street
Roger Johanssen proves that the web is a global community. While he lives and works in Swedan, his posts on web site accessability are useful for anyone working on websites.

UIE Brain Sparks
The staff at User Interface Engineering share their expertiese on their blog, Brain Sparks, on a regular basis. Speakers at their conference and others they work with also post periodically as well.

mStoner
Michael Stoner is a consultant working with higher ed and non-profits to improve their electronic marketing, including web sites. The information on his blog tends to be strategic in nature, what's happening in the industry, etc.

College Web Editor
Karine Joly is a web editor for a liberal arts college on the east coast. She does a nice job of following trends in higher education and the web, although she can sometimes be too quick to declare something of significance or to broadly proclaim a tend as applicable to everyone in higher ed (in my opinion - your milage may vary).

Higher Ed Marketing
Andrew Careaga, director of communications at the University of Missouri-Rolla, is very well-respected in the communications area of higher ed. He writes about PR and the web, and often has interesting things to say.
