If you ever wondered if anyone has ever done a scientific study on IM, they have. None of this really suprises me — I’ve been using IM since we got the internet (I think this was sometime around 1998, but I’m not positive), so I have some experience with it. There are other links at the bottom of the page that are also worth checking out. And once again, the “Top 10 Useless Limbs (and Other Vestigial Organs)” thing. Maybe I should bookmark this site.
