I don't want to broaden this too much, but you feel the BBC has to support Saf 1.3 with 0% market share because you don't want to force a software update on those 80 odd people whilst on the other hand transitioning to digital forcing a hardware change/purchase on the entire user base?? Seems a bit of a weak argument. If indeed (as reading between the lines you appear to suggest) if a javascript framework needs to be hobbled to support screenreaders (good!) and obsolete browsers (bad!) then it may not be right to weigh in with one of the top frameworks. But you asked them first though right? "More or Less" is great. But if commercial radio had a free-to-air program "Less or More" and the only difference was that you transmit at a frequency that's better for reception on crystal sets then I'd hope the BBC wouldn't bother but would add to the diversity of broadcasting some other way.
