I'll make one soon, just thinking of a good name for it.
Description would probably be something like Faucets, pay to click, web based games, and other services primarily based on ads and/or micropayments. I think that covers the targeted sites well and doesn't include any that shouldn't be.
Faucets is a little too specific, free bitcoins is misleading. Micro something?
Thanks for this BadBear! Micro Earnings would work.
