Asbestos
Apparently asbestos is big money these days.
This guy has set up a blog relating to asbestos to try and get some of the revenue from click through ads. Read the post about it here.
It seems interesting that someone would set up a blog just to make money, but it does seem to have relevent content, so it will be interesting to see where it goes. I will be keeping an eye on this I think. See this page for the story – it was also on slashdot a while back.
