TweetDeck is falling apart after Twitter’s rate-limiting fiasco

Yeah yeah, they've broken the old TweetDeck. You need to wait for the pop-up to ask you to transition to the new TweetDeck. Or, search on the internet for the Javascript variable you have to change in your console.

The more important question is that they've removed the Activity feed, where you could see likes from other people. Which was like a realtime feed to what your friends were doing on the website. The website is way more boring now.
