I noticed the occasional cache issue has snuck in again. It was only showing posts on the front page from back to July 19th. Since we update daily, sometimes twice daily, that's a problem! I just deleted the cache, so it should be working now. Don't forget to check out all the posts between the 19th and today that you might have missed.
Please, if you ever notice the site hasn't updated in a few days just drop us an email.
