Making money online through Adsense and other ad networks

AdMoolah.com is a site "Where webmasters can share and compare Google AdSense income". If you are comfy with such, register here.

However, I don't know what valuable insight can one really get from learning about every other webmaster's earnings. Can't forums with AdSense threads inform us enough of AdSense earnings benchmarks?

But it is a good way to see that people really are earning money in adsense.  Its good to know that some people do but it is even nice to see the actually income they had.   

I call it, a belief builder.
