Planetmath.org switched to this some time ago and I can't stand it. After initially displaying as a bunch of LaTeX, the entire page goes blank for 5-10 seconds as JsMath does its thing. So incredibly annoying, especially since I am usually just trying to glance quickly at a theorem or definition. I don't know why they didn't switch to MathML, which is supported by any browser someone reading math is likely to use, and is awesome. On that note, does anyone know how to get Wikipedia's MathML display mode to work correctly? I have it set in my profile but it doesn't do anything.
