My three-year-old son knows what a blog is. Because his dad blogs? Nope, we can thank PBS Kids. During our most recent trip to the library to 'play' on the computers he said, "Daddy, I go to Buster's blog."

Buster of Postcards from Buster has a My Blog section on the show's web site. Immediately after the show Buster tells kids to visit his web site and look at his blog.

The blog documents Buster's travels as he visits various locations on the show. The current entry is for Mandan and Bismarck, North Dakota. The section is really a blog in name only since it is not dated, does not allow comments or trackbacks. There is a pulldown menu on the left that lists his previous entries though.
