I converted from Google's Adsense (on iBLOGthere4iM), which was paying me $0.26 CPM to Bidvertise.com today. In part because I'm a little upset at the low paying Adsense and in part because I want to experiment and check out new stuff. I'm getting $0.01 per click right now on Bidvertiser, but I assume that increases as more advertisers become aware of your site.
Update: Early results are showing a CPM below $0.01 :(
