I love Tweetbot, I love that it syncs between iOs and Mac. I like having a chronological timeline, I love that it keeps where I am in the timeline, I like the interface with the side swipes, etc.

This is a terrible move by Twitter. It might be a relatively small number of users, but it's mostly power-users and super-fans, and this needlessly hurts them.

If Twitter wants to make more money from them, just add ads in the third party stream. Don't try to kill third party apps.
