I've just been doing a very quick bit of research into the Wizard of Oz approach to usability studies (by which I mean checking it meant what I thought it did) and somehow ended up at Wikipedia's page on Political Interpretions of the Wonderful Wizard of Oz. I have a feeling I've seen some of this before and promptly forgotten it all, but it's amazing that:
1) People can draw so much out of all these things. Whether it's on religious grounds or political it seems that something like this exists for almost any kids story, classical novel or well-known film (and probably some lesser known ones too). Maybe I'll have to go looking for some more but there's always the classic Lord of the Rings religious arguments :) Even on the poetry front I sometimes have to wonder how much of the subtleties and double meanings were *really* intended and how many just worked out that way - did people really write all those GCSE anthology poems with so many meanings?
2) That people can contribute so many details to Wikipedia :) It's strangely addictive.
