Well, I moved my blog over from myblogsite dot com, because they sucked ass. Well, overall it was an ok service ... until they started messing with my posts. You see, they take words from your posts that could have advertising potential, and turn them into hyperlinks to advertised websites. So if you used the word "dating" for instance, it would turn that word into a hyperlink.
I don't mind ads, but I don't like them turning my posts into advertisements. So, a friend recommended blogger.com, and here I am.
