I'm thrilled to announce that Posterous has been acquired by Twitter!
The opportunities in front of Twitter are exciting, and we couldn't be happier to bring our technology and expertise to hundreds of millions of users around the globe. Plus, the people at Twitter are genuinely nice folks who share our vision for making sharing simpler.
Posterous Spaces will remain up and running without disruption. We'll give users ample notice if we make any changes to the service. For users who would like to back up their content or move to another service, we'll share clear instructions for doing so in the coming weeks.
You can find more information answers to other questions you may have here.
Finally, I'd like to offer thanks to everyone, especially those who have been with Posterous since day one. The last four years have been an amazing journey. Your encouragement, praise and criticism have made Posterous better, and I really appreciate everything you've done.
Thanks again and I look forward to building great things for you at Twitter.
