Started using twitter feed

I've just started using twitter feed.

It is supposed to automatically tweet using my blog post's title in the associated twitter account.

I had already connected my twitter account to my facebook status.
So from now on, when I write a blog post, there will be an automatically generated tweet for the post, and a facebook status update.

Guess what? Facebook offers an application to update your twitter as well! What if I set both? Do they check for "circular automated updating"? Does such a thing exist?

Look all the power I have. I can push the entire internet in an infinite loop!
