It is through referral deals. People offer you to register under them and they will pay you after reaching a certain number of clicks in that site. Isn't that great?
Okay I get it now, someone explained it, it sounds okay, but I'd better stick with the bunch I have already. It's hard enough trying to keep up with neo and Buzz and a bunch more, but good luck in all that you do.
I have seen deals like that before but it does not always turn out to be as good as what they speak of. It takes quite some time to be paid or reach payout alot of times.
