One minor thing ...

that is annoying about Blogger is no strikethrough shortcut in the posting tool. There is, however, a lot of conveniences I'm loving, such as a handy revision link for the blogger after each entry (when logged into your account) not to mention a text color button, useful for making horrifyingly garish entries.

The handy Perfomancing Firefox add-on has the shortcut, and a lot of other handy shortcuts, like del.icio.us bookmarking, technorati tagging fields and pinging. It works well with many different blogs, including Typepad and Blogger.
