John Voorhees, writing at MacStories on Twitter’s removal of the old API that powered apps like Tweetbot and Twitterrific:
How these changes shake out for third-party clients remains to be seen. I’ve used the beta update for Tweetbot over the past week, and the elimination of its Stats and Activity section has left me feeling like there is something missing from the app. I still prefer it to the official app, but the removal of that section is a meaningful loss. A similar hole will be left in Twitterrific when the Today section no longer works. Both apps have also lost their Apple Watch apps and live-streaming. If those are critical features to your use of Twitter, you may want to give the official client another try.
And:
How long third-party clients will continue to be a viable alternative to Twitter’s official app is anyone’s guess, but for now, I still prefer the experience delivered by Twitterrific and Tweetbot despite their limitations. I turned off all Twitter notifications except for direct messages a few months ago, and I haven’t missed timeline streaming during the Tweetbot beta. Notification delays for direct messages, which are noticeable, will probably affect my Twitter usage the most, but I have plenty of other ways to carry on similar conversations. As a result, these changes don’t make third party clients unusable for me, but it has caused me to reevaluate which Twitter client I will use going forward, which is a process that is ongoing.
Sigh.
