RSS feed problems

You've probably noticed I'm experimenting RSS feed issues. 50% of my RSS feed articles are not visible. I'ts due a "content type" tag set by blogger atom generator. SOME RSS readers are not capable of reading <content type="application/xhtml+xml"> articles, but only <content mode="escaped" type="text/html">

I don't know when "application/xthml+xml" mime type is used, but I've asked technical service for more info.

I guess putting more HTML tags will probably

• force atom to use html mime type
• make things look weird
• astonish the masses
• force my RSS reader read these articles
