Reminds me of a company I worked for back in the dot-com boom days. MostChoice.com planned on being some sort of meta insurance company, but that failed and the hundreds of pages of content they'd generated about insurance and financial planning, etc. stayed on the web. I would check on them over the years (to laugh at the fact my code still existed) and it seems they made more money as a static site just on AdSense clicks than they did with the original business idea. Insurance clicks are very nice.
It looks like they've redesigned the site now and taken down much of what I wrote. Too bad. I was a sophomore in high school and it was exciting to me to have my financial planning calculators out there on the internet.
When I ran a somewhat large music site(100K uniques/day), we'd make significantly more money from adsense when our streaming server went down.
Why? Because when hitting the play button on the player didn't work, people start clicking on the ads.
