Oh, no, not another TLA!
I'm continually surprised how many people around me do not understand RSS. Actually I don't mean UNDERSTAND (only geeks need to understand) I mean have a basic idea of why and how to USE the results (and everyone needs that - even if they don't realise it). Common Craft have a neat short YouTube RSS in Plain English video to explain!
BTW thanks to Nichthus for pointing me to Common Craft's You Tube output (their item on Wikis at last enabled me to see what apart from Wikipdedia they are good for) (-;
