As to the "new" Blogger system. . . I gotta say that I like it. Having built-in categories (Blogger calls them "Labels") is nice (less code to load/work with), the Archiving system is pretty sweet, and best of all, no more Endlessly Rotating Triangle of Publishing Death ("Old Blogger" users know what I'm talking about). Plus the backend is a bit easier to work with. Gotta love instant changes to template/widgets/etc.
I guess I'm happy with it. Now if I can just, y'know, keep publishing new stuff. . .
