Over on the the Blogger official blog they just announced that a new version of Blogger is being rolled out, Blogger Buzz: Blogger in beta:
"If you can't wait, you can create a new account on the beta now and make a new blog to test out the new features. Because the new Blogger uses Google Accounts, you can use your existing Google login, or create a new one. (Later, you'll be able to merge your current and beta accounts, and have all your blogs in one place.)"They're adding categories! Finally. There's also drag and drop features to that allow you to change how you blog looks including easy ways to manage content on your toolbar.
I created a new blog, Nokia N93 Test Center to check out the new features.
