<b>470</b>Your plugin does nothing to format special characters within the content. I was using this plugin on a large site with a lot of posts, and had a huge issue parsing the XML from the feed because of a single “&” that was interpreted as meaningful.
Could you at least add CDATA tags around the content, so that it is not interpreted by XML parsers as something other than content?
Otherwise, I like what this plugin is doing.
