On February 15 2013, Sachin Agarwal (Founder and CEO) announced the end of Posterous. Posterous will be turned off on April 30, 2013 as a consequence of the acquisition by Twitter almost a year ago. Users can download a backup of their posts and are suggested to move towards WordPress or Squarespace as they both provide importers.
In the future, every time somebody starts an argument about using a existing platform as company website he will get the answer: “Remember Posterous”.
