OT: Beta Blogger

I haven't investigated this much, but I got an error recently trying to post a reponse to another person's blog the other day and it gave me an error saying I couldn't. I can't remember the exact error, but it had something to do with me recently merging to the new beta blogger. So, if someone is trying to post a response here and gets the same error, I guess I'm screwed temporarily as I can't seem to revert back to the old format. Bah!
