Your parents are on Facebook. They are still uncool. Presentation tips from Edward Tufte. I recommend his books The Cognitive Style of PowerPoint: Pitching Out Corrupts Within, Second Edition and The Visual Display of Quantitative Information. The best new game I've seen in a while: Wiki Paths. You are placed on a random Wikipedia page and have to navigate to a target page within 5 minutes, using only the links in front of you. Fun.

Liked what you read? I am available for hire.
