"face it: the # buyers is very limited indeed, while the # new pics that can be produced is unlimited"
The number of possible buyers is the same as the number of possible contributors. And the number of uses buyers can come up could be just as unlimited.
Hey-hey, It's not the number of contributors but number of images... but it's pure nonsense anyway, every prodouct has a limited market even coca cola, and this isn't nearly as everyday as drinking, is it? Do you seriously think there will buyers popping out of the void at the rate ppl can cram acceptable images out of their digital cameras?
