Daring Fireball: The End May Be Nigh for Third-Party Twitter Clients:

(Twitterrific for Mac is still functioning, though — at least as I write this. Unlike Tweetbot, Twitterrific uses different app IDs for iOS and Mac, and whatever is going on, it seems to have affected only the most popular third-party apps.)

The fact that certain apps/API IDs haven’t been swept up in this reads to me that it’s an intentional shut-out, and that Twitter has shot itself in the foot deliberately. Even before taking hiatus over the antics of their Austin Powers Villian leadership, I never willingly interacted with the service via their website, only through third-party clients… And I’m absolutely not alone in that.
