It's interesting, yo!

Ebay behaviour.

I'm reading it, and it corresponds to so many things I do. I'm a casual ebayer, it's really interesting! Game theory (Hi-larious) proves that both sniping and non-sniping behaviour is rational; some people look at ebay with a view of getting the item, some people look at it in terms of economic behaviour (minimising consumer surplus, budget constraints, irrational behaviour), where people pay the maximum price for a product they're willing to pay, some a combination...It's all very trippy.
