Facebook is now paying its users

I’ve noticed that many SiteTalk supporters complain that Facebook is reluctant in paying its users while they make millions of dollars in revenue. To SiteTalk supporters, this is simply unfair. Hence, they would argue that SiteTalk is a better social network because profits are shared.
However, according to Mashable, Facebook has just recently introduced a system where users are paid to view certain ads (at 10 cents/ad). And the credits earned can be used to purchase goods on Facebook Deals.
