The Oatmeal raised Tesla up, and pummeled Edison into the ground. Here's an ever-changing Twitter search that will surely prove my point: https://twitter.com/#!/search/edison%20tesla

Edison was a great inventor, and an incredibly hard worker. He was a persistant and effective business man when it came to spreading the adoption of world-changing things like the lightbulb. He may not have invented it, but he built and marketed the first one that was actually practical.

The point: Every geek in the world needs a little Thomas Edison in him.
