I've noticed something interesting about Blogger. Every time I try to post something, it tends to end up a little wonky. Typos aside, the formatting tends to get all munged up. And I don't think I ask too much -- large font, Verdana, single spaced.
I've since remedied the situation by composing in Notepad, and then copy/pasting into the "Compose" field, and adding links and formatting as necessary.
