I'm not ditching Google Blogspot completely because I like their authoring interface. But I've managed to port my writing over to my own site and since Google AdSense screwed me, I'd rather not send them any traffic.
Nothing changes from the reader's perspective except that you can reach the site the following ways:
www.alaskapade.com
alaskapade.com
or
http://alaskapade.blogspot.com
