What it was
A formally launched blogging and group-sharing platform founded by Sachin Agarwal and Garry Tan.
Users could email text, photos and media to personalised sites, with the service automatically formatting and distributing each post.
Existence timeline
The service opens email-based blogging to ordinary users.
Publishing, cross-posting and private sharing develop around the core email workflow.
Twitter buys Posterous and its engineering team.
Users receive an export deadline and migration guidance.
Posterous blogs and applications become unavailable.
A short extra period allows remaining account exports.
Why it ended
After Twitter acquired the team in 2012, Posterous announced that the service and all public spaces would close on 30 April 2013.
Last confirmed trace
User exports, Internet Archive captures, screenshots and the Posthaven successor preserve portions of the vanished blogs.
What it left behind
Its email-first simplicity remains a benchmark for reducing the distance between creating something and putting it on the web.
