When Google stops making it so lucrative for spammers to generate all their crap ... maybe the end user will finally see some respectable search results.

I agree that AdSense has been a boon for the get-rich-quick crowd, but overall, I'd say there's less spam in Google's travel SERPs than there was a few years ago when boilerplate affiliate pages dominated many if not most travel searches. If AdSense went away tomorrow, we'd still have machine-generated sites with millions of keyword-driven "post a review" pages. Those pages are so cheap to generate that they don't need AdSense to justify their existence financially--they'd be making money even if they had to rely on run-of-network banner ads.
