Looks like Blogger has undergone a redesign. This site says they are using a default template. Pretty nice, I'd say. CSS is a beautiful thing. A complete run-down of the redesign code-fu is posted on Stopdesign – an all-star cast contributed to create the templates. (Complete images of the new blogger templates.)
Good job by the folks at Blogger to take a huge step forward. Add trackback-ish functionality and I'd almost thing of using it.
