Me, 10$K/month. Because of AdSense revenue, I took many hours building a new website (online since last month) and hope that website it will eventually make some money. I really don't like having ads on website I visit but don't use AdBlocker (hide it behind other windows). I think WikWik.org is a great site (I'm the author) and for sure would not have exist without AdSense opportunity.
