I don't run Adwords and this morning I'm bored... so I read this. :)
Seriously, I've been reading the adwords/adsense threads here for a year or so trying to make up my mind to jump in. My hobby site linked to my moniker has no monetization. My commercial sites are all direct market supported by print, radio, tv and do well enough. I suppose I should take the plunge and at least look at the "google thing" to see how flawed... er... useful it might be. One of these days.
And one of these days I might post a FOO like yours! :)
