TED just posted a talk by John Hodgman (of pretty-much-everything fame, but most notable as "PC") that should cut straight to the heart of any geek. I could say that it involves lost time, aliens, a summer day, tourism, Liberians, the reliability of buses, and true love, but that wouldn’t do it justice. Just watch it, it’s only 16 minutes long and available in a variety of handy video formats.
