hmmm. I don't think I'd tweetstorm a blogpost. Perhaps, if it were a huge post, I'd want to put some choice quotes into a tweetstorm all with links back to the anchors in the post. But the UI thing is a little overboard.
Of course, I tweetstorm my posts which also head to Known, 10Centuries, and micro.blog. But that is an external tool. I wouldn't want Known to change their UI to accommodate twitter.
