In a written statement to TechCrunch, a Twitter spokesperson had the following to say about the company’s new direction with regard to bots:
@MagicRecs is no longer regularly sending recommendations through Direct Message. Recommendations that were previously shared via Direct Message are now delivered via push notification.
Magic Recs (which Twitter always tagged as an ‘experiment’) was one of the few useful bots around, but required you to follow the account (you know, DMs and all that). It also didn’t have many followers: 112,000.
Not that push notifications are much better than a DM, but it’s probably just Twitter streamlining its efforts; the engine powering the recommendations is still alive (as is the account), but Twitter will no longer be feeding you DMs.
