... how about calculating the entire income of eBay?

1) Add up the feedback scores of all the registered members (this may take some time)

2) Divide by two to give the total number of transactions.

3) Guesstimate average sale price - say £10.

Multiply (2) by (3)

Take 10% of the result - that's about what eBay/PayPal get.

Would that not take at least a million monkeys a million years?

Oh noooo...another eBay-related thread. You've really got to try and tear yourself away from eBay. It can't be healthy!
