What's not getting clearly distinguished in this thread is the difference between foolishly depending on Google and actually being independent of Google. No website is really independent of Google - except maybe Facebook and Amazon. But even they would feel a noticeable drop if Google banned them tomorrow. There's no site on the web that wouldn't reel a little if suddenly the Google traffic went away.
But I think travelin cat was talking more about relying on Adsense for your whole income stream, and/or Google search for all your traffic-driving efforts. That is certainly "depending" on Google in a way that's going to make it hurt extra bad if they ever pull the rug out from under you. But the fact that Google makes up a big percentage of traffic for most decent sites, no matter how hard they try to build other traffic streams, is just a matter of numbers. It's nerve-wracking, but it's a different issue from willfully depending on Google/Adsense while they're still loving you.
