Tweet Marker’s time has come and gone. I’ve notified developers using the Tweet Marker API that I plan to wind down the service by July 1st. I’ve also cancelled all the paid subscriptions. (Actually I haven’t billed anyone in over 6 months, so I’ve been running the service for free.)
Over a million people have used Tweet Marker. I’m proud of that. If you’re one of those people, especially if you supported Tweet Marker as a developer or with a subscription, thank you.
There was a short time when I did indeed use Tweet Marker, when I was juggling between an iOS and Android smartphone, but that didn’t last long. And I never did understand why Twitter itself did not choose to implement a timeline syncing feature — this is probably their largest technical fuck up.
