I am joining the posters of the below comment. Fix the RSS.
I think the PHB has gotten control of your website. At least, that's the only explanation for not providing the comic in the RSS feed. The only reason not to put the comic in the feed is for pageviews/monitization. THE. ONLY. REASON. If anyone tries to come up with a technical explantion, THEY ARE LYING. Scott, if you made this decision, then I am very sad and disappointed. If not, then you need to have a discussion with Universal/Uclick about their practices.
