The abstinence-only education comparison is catchy, but frankly I’d go further. Even that description likens the ‘webby’ tools to underage premarital sex — stuff we ‘authorities’ would presumably prefer the ‘kids’ not do at all, but about which we differ only in how hip we ought to be to the fact they are doing it anyway. But a lot of the well-timed Googling and Wikipediafying you describe is the most appropriate thing to do. They’d be fools not to, and if we seem to be teaching them some kind of puritanical Google-aversion the only result of it worse than our being ignored and dismissed as foolish old fuddy duddies would be if that instruction was actually taken and followed. The trick, of course, is teaching them to understand what they are really doing, and what they are getting out of it.
