RSS, will work for your posts, most CMS/Blog systems have the feature to import from a RSS feed, in my case I'm using django-zinnia. $ python manage.py feed2zinnia http://blog.grupones.com.bo/rss.xml And it's ready. I'm looking into the API to export users and subscribers, once I have that will be all. (Right now the posterous api site is down) However I must say, I'm not happily moving out, I love posterous, I will miss email integration, and user management. It's nothing that I can made by myself, but was nice having that features with out developing. PD: There is also this guy → https://exportmyposts.jazzychad.net/ https://exportmyposts.jazzychad.net/ that made a more complete backup using posterous API, you can buy it starting from 9$us. There is nothing someone can develop using the posterous API
