I'd[0] be fascinated to know people's reactions to this. Material explaining this sort of thing has been around for what seems forever - do people find articles at this level useful? I know it won't be for everyone - some already know it, some don't care and don't want to bother - but some will find it useful, I'm sure, and I'd be interested to see some feedback.
