I have tested ClixSense for two days now and it still seems to work ok. But one problem that I recognized immediately is that if you are not a premium member (a one time fee of $10) you only get a few ads a day (or so it seems to me). In the backoffice it says that there are 525 premium ads, ads only available for premium members.
Yesterday I clicked on about 10 ads, today there are only 2 visible on my list. Maybe more will come soon, but there will be pretty hard to earn more than a few dollars a week if you don´t get enough ads to view. I will keep you posted about the developments at ClixSense.
