Although not a great user of twitter, I have used it as a way of conveniently getting messages from devices like my Kindle through to my blog. Yes, I was doing it to post to the blog, but twitter gained the traffic as well.
Except that has now stopped, with changes to twitter’s API policy. They want anything posted to twitter to stay with twitter, and not be exported or cross-posted to any other system. As a result the IFTTT website has had to remove all of its twitter triggers effective today.
Because of this, I no longer have a reason to keep twitter going, so I am deleting my account. I want my content consolidated, not fragmented over several different walled gardens.
