AdWords
Google's AdWords, bless their heart, have been trying desperately to get people to click on their ads. Here's a sample from Lindsay's page.
It seems AdWords is going after that niche market of folks who like to vacation in parts of the world that have plentiful amounts malaria, cholera, and dysentery. A few months ago I read about this guy who travelled to Cameroon with the intention of infesting himself with hookworm. Apparently hookworm can "cure" asthma.
So if that guy is reading Lindsay's blog maybe AdWords can help him find some good travel deals should he need to go back.
