The most surprising news about Tweetdeck being broken is that Tweetdeck is still alive. I know press would riot if not got killed but that sounds like even more incentive for him to kill it.
BAHAHAHA, this will work out well! They really would've been better off just shutting it down completely.

@paul Uggg, I switched over to new TweetDeck, believing the text that says I can always switch back.

But I guess that text is old, because on mine at least, it's impossible to return to the old DDoS version.
