This week, Jonathon Delacour is reviewing Joe Clark's book Building Accessible Websites, which I mentioned in class. He's also interviewing Joe about the book and accessibility in general. Along with Jonathon's excellent posts, you can find comments by people like Mark Pilgrim, whom I also mentioned in class.
We'll "dive into accessibility" in more depth after the break, but these are great "bite-sized" pieces of content for you to chew on until then.
