I just posted a comment to this Raiders question, and bolded a few words - which show no changes. (I also just bolded "bolded", which isn't showing up here either :(
Does the font used for comments on the main site display bold/italics in the Opera browser (V10.63)? (It does work in Firefox).
And unrelated to browsers, is black-on-white a good choice for meta's text? (Personally I can't stand it :)
