I'm certainly nowhere near making a living, but I have a few simple tools that generate adsense income. The sites generate international shipping documents. It was something I needed myself. Targeting businesses in a small niche helps with the per-click value and organic search rankings, I believe. So I don't need a huge number of visitors. I feel good about actually providing value. And they are useful tools for me and I make a little money (about $150/month). I've made a few consumer-oriented tools, including a baby name site, a meat temperature guide and office football pool site. I have not generated enough traffic to make ads worthwhile, but I suspect the pay-off would be low anyway. These sites would require thousands of visitors a day, and it would take a lot of legwork to generate that sort of traffic.
