We just moved our content from Tumblr to Posterous simply because we find the user experience more engaging and it allows everyone in the office to post to it. If you follow us on Tumblr via RSS, Posterous will post automatically to it so no need to update if you don’t want to, if you’re still into the old school way of typing in URL:s (how easy is http://anomalousness.posterous.com to get right the first time?) please come here in the future.
