Someone complained to me about my RSS feed being broken.. for some reason his reader doesn't allow <author> fields with email-addresses between < and >. I've changed it to emailaddress (Name), but I feel like this is a bug in his RSS parser (I escaped the <s and >s for a reason).

Or did I just land in double-escape hell and should I use crazy stuff like &amp;lt;, even though Feed Validator thinks my feed is valid?

Update: It seems that Planet Ubuntu is un-escaping, but then does not re-escape when it writes its own feed. Also, it doesn't seem to pick up the change I made to my <author> fields.
