What I find most compelling about it is what it says about our culture - not just in a "what will we sink to" reality-show kind of way, but about the talent crossoveer between what job segments are both tech-savvy and unemployed. The key to keeping this site popular will be moderating the results so that "interesting" things stay at the top - if it gets popular enough that, eBay-like, it requires a sophisticated search engine to find anything more than "I will give you a link that answers a question you might have"-type offers.
So Paul, do you feel ripped off now, knowing you could be making five bucks for a book recommendation? It kind of reminds me of the time when my friend told several of us that her mom was a sex worker and got about $200 per blow job (not sure how true it was). The rest of us - all women, all married to men - got real quiet and thoughtful-like for a second until one piped up and said what we were all thinking, "Shit, I've been giving James free blowjobs for twenty years. He should at least do the fucking dishes from time to time if he ain't payin' for it!"
