I'm certainly not the first person to get on the RTF to HTML bandwagon. But that didn't stop me. The goal was to get syntax hilighted code from Visual Studio to my blog in the fewest possible steps.
Update: There seems to be some issue with the colours on this page, however over here it seems to work fine.
Update 2: The problem seems to be in the JScript/HTML rendering, for some reason newly output CSS classes are not overriding the previous versions.
