Very promising new blog.  ProgrammableWeb.com from John Musser:  "Content to include news, reviews, comparisons, and examples. Formal APIs, unofficial APIs, and accidental APIs are all fair game. Anything ‘programmatic’ that’s publicly accessible online."

The way I discovered it is kind of cool, too.  I added Don Loeb's RSS feed of saved pages from MyWeb to my Bloglines reader.  Don doesn't blog, but he's an excellent source of what's going on out there.  Fortunately, he tracks interesting things publicly, and we all can have a view into that via RSS.
