In response to the urgent requests of absolutely nobody, I've added an RSS 2.0 feed to the blog. It should be (um…) over there on the right side somewere. (UPDATE: ah, there it is.)
Much gratitude is due to Pete Freitag's web page "Howto Create an RSS 2.0 Feed" which (unlike many other sites) just describes what you need to do. So good on Pete.
Also the stylesheet for the feed was shamlessly ripped off from an article by Evagoras Charalambous "Improving an XML feed display through CSS and XSLT" Good on him too.
