www.admoolah.com is a fascinating site - I just found it, and it lists stats about Adsense earnings for different websites. Very cool to see what other people are actually making!
I see your point, trader, but I still think it's a pretty cool site to see what's going on with Google earnings. and it'll likely continue to grow, giving us a better idea of what stats are average.
Dimva - that's exactly what it did for me too. I thought - hey, if that blog can make THAT much, then if I work hard enough then my sites can make a fraction of that a day...
