i see Yahoo in their se optimised pages add an extra comment tag stuffed with keywords in their headers:
<!-- Keywords:
in addition to the usual <meta name="keywords"
anyone played with this and seen a difference in rankings?

I thought the trick was to put it inbetween the header section and the body section of your page. A really spammy method, and I never got around to actually try it anywhere.
