Posterous has choked every time I've attempted a Tumblr to Posterous import. From outright failure (which could be simply that Tumblr API was inaccessible) to even upon "success" notification, seeing that it only brought in ~300 posts from a total of 20K posts. Perhaps 20K posts is too burdensome a task, but ~300 is a paltry amount.
