Here's a piece of Inside Guardian whimsy - the Guardianwhack. I've been playing about with our URLs recently to find interesting content based on combinations of the words we tag content with. For example, here's a URL which will give you dead rock stars:
http://www.theguardian.com/music/popandrock+tone/obituaries
And here's one which will give you stuff about films and food:
http://www.theguardian.com/film/film+lifeandstyle/foodanddrink
See this post for more details on how to create a tag combination. Now, if you're familiar with the Googlewhack you'll know what I'm talking about - you submit two words to Google in an attempt to return just one result. By combining our tags you can try the same thing using content from the Guardian site. Combine two tags, and try and return just one article, video, audio etc.
Here's some we've found so far - it's harder than you think:
From the ordinary:
http://www.theguardian.com/business/economics+media/apple
to the outré:
http://www.theguardian.com/stage/wertenbaker+sophocles
And from the topical:
http://www.theguardian.com/lifeandstyle/catwalk+environment/climatechange
to the unexpected:
http://www.theguardian.com/lifeandstyle/texmex+breakfastrecipes
Have fun!
