Before you ask the question how to switch your blogger account to this new service, there's a few Cons you need to know.
From what I read on several blogs who have made the switch to Blogger in Beta, you can no longer edit the template manually, only with the WYSIWYG template editor. Does this mean you can't add plugins like your blogrolling blogroll, or use offline posting tools like Qumana for your blogs, or updating through Photobucket to post videos and pictures? Don't know! But John over at Freshblog informed me that manual template editing in beta is apparently coming within days!
