I had to do it, dedicated servers cost a lot of money each month, and this was one of the only ways I could easily cover the cost per month. I have used Value Click Media and they pay a nice $4.75 per 1000 impressions, on which i placed them on Profile Styling and soon to be placed on Cute Layouts. The good thing about these impressions is that they only show once per IP every 12 hours. So you wold goto the site once, see the popup, then never see it again for the whole session, unless your on the site for 12 hours, but I dont think anyone is that addicted to these sites of mine.

SuperCarNews has been getting an average amount of hits, set to break last months visits record. I have also done a sitewide link exchange with AllDreamAutos, hopefully this will bring in some traffic, as that site recieves over 7000 visits a day.
