This left me wondering how to move a year+ worth of blog posts from Posterous to WordPress. A quick search found a WordPress plugin called Posterous Importer. It worked reasonably well but it did leave some content behind, almost arbitrarily, on Posterous’ S3 instance. I should probably download and re-upload that content at some point before shutting down my old Posterous site. I’m sure I will get to it at some point :).
