i dont, but from the values i see some people having (just)from google adsense i think it´s totally possible. But if you live from the net you´ll need to have a big amount of work... not easy to keep up having lets say $1000-2000/month
It is possible, but it's not too easy. I have plenty of site visitors, but nowhere near as much Ad revenue as I'd expect. Google just kept dropping until they weren't worth keeping. Now I'm looking for alternatives.
one thing is living of the net, another one is "what do you do when you need to work to pay the bills and you need an great amount of time to work on your sites." it´s not easy, and lets just imagine what if google adsense closes... of course there are alternatives but....
About a third of my income comes from the net, but it's not nearly enough to get me to quit my day job. I think I'd have to be earning 7 or 8 times what I do now to justify "retiring" from "regular" work.
