OK...A lot of people can't post comments because it asks you to 'Comment As'.
The drop down screen gives you the following options:
Google - LiveJournal - WordPress - TypePad - AIM - OpenID - Name/URL - Anonymous
My Blog (Blogger) is run by Google.
I found it a bit confusing at first (but aren't all new things??)
But in general, it was pretty easy to start.
