A colleague of mine (Geert) pointed out this site did not work well under IE6.
I fired it up and sure enough, it did not show the blogposts, all was black.
I also tried in Firefox, but that worked nicely.
I went through my stylesheets, while trying out stuff in IE 6.
It turned out to be 1 line that worked nice in all browsers, but not in IE 6, I removed it and now I'm cool again.
Thx Geert, for pointing this out.
Goes to show, trying out as much browsers as possible when building web apps is no luxury!
My thoughts exactly...
