Boagworld was one of the first blogs I started to follow when getting into web design. Paul Boag and Marcu Lillington host this podcast for all of those people who are working with websites on a daily basis. Most of the blogging content is directly related to the audio podcast they also offer. I personally listen to the podcast and then read any articles that I feel need some more attention. Always a fun time listening to them baner.
While A List Apart doesn’t have as frequent a posting schedule as some other blogs all of the information provided is invaluable.

Run by Chris Coyier, CSS-Tricks is an awesome resource for all those starting to tackle CSS. I know that CSS can feel overwhelming at times so the tools found here are very helpful for those starting to tackle it. CSS-Tricks contains not only a blog but also forums and screencasts. The forums are a great place to get help with code and the screencasts can even remind veterans of some of the simple shortcuts they forgot. For a great intoduction to WordPress check out the screencasts on Designing for WordPress.

I Love Typography is a blog entirely about fonts and beautiful typography. An absolute must for those designer who need to beef up their knowledge of typography in general. Without a good knowledge it is much harder to judge what is worth doing for the web.
