The perils of a high google ranking

My 6/03 entry about Fear Factor shooting in Griffith Park has generated 12 comments from people who think I'm Joe Rogan or have some way to get him a message... (Several visitors to that post have come after searching for "fear facter"; that was a mistake made by one of the commentors, not by me...)

I'm also top ranked for the phrase "sell your body to science". The entry dealing with a spam message I received has now generated 25 comments from people who want to sell their body to science.

Why am I not making money off these people?
