HTML in RSS TITLE nodes

Man, I subscribed to Reiter's Wireless Data Web Log in my aggregator and I see escaped HTML in the ITEM / TITLE nodes. The 2.0 spec doesn't specifically say text only in TITLE nodes as far as I can tell, but this is a deal breaker for me. I look at HTML all day long. I don't want to read through it at home. Unsubscribed.
