> Don't forget that with AdWords you can reach niche sites...

That is true, BUT, since AdSense brings in pennies for the webmaster in general, relative to the other options, a lot of good/non-shit niche sites are not using AdSense, but are either using custom sell space or other targeted networks that payout 2-10X of what Google AdSense does.

IMO, if you are serious about running and monetizing a business, you will get as far away from being 100% dependant on the Google index and their ad network as you can.

So many people have been screwed this way. Imagine what would happen if you dropped a couple of pages down in the index tomorrow, or your AdWords account was banned.

Though I'll still admit there are a couple of sites I can no longer target, because they use AdSense ... but I have considered emailing each one and offering 2 or 3-times whatever they get with AdSense to get rid of it and put up my ads/links instead.
