Upgraded to the new Blogger platform today.
Not sure what happened to our profile names in the upper right.
Maybe they'll come back once everyone has logged in
(you have to log in with a GoogleID rather than your Blogger username to post now).
The main change you'll see is the addition of "labels", also known as categories or tags.
I've gone back and begun to tag a few posts, and we can begin to see some trends.
Let me know if you need any help.
