"immensely tedious" Aye, there's the rub. IT'S NOT FUN. Disturbs me that on Netflix I've rated six-hundred-and-fifty-four movies - that's a huge amount of "$#!^ work", yet I did it compulsively and enjoyed it. That's the whole thing about "crowd sourcing", "data mining", etc. - persuade people to WANT to do the work, and they will with little complaint. If your users are viewing it as "$#!^ work", you've done it wrong.
