If you are an RSS subcriber, it's possible that the link you have doesn't work anymore. I'm getting reports that an Atom feed has suddenly stopped working, and am baffled as to why it worked in the first place.
Please check to make sure the RSS feed you're subscribed to is the right one. And for your reference, the right one is Feedburner: http://feeds.feedburner.com/DeusExMachinatio
Apologies for any inconvenience, grief, or other manner of woe this might have caused you.
