One of my favorite things to do is swing by Wikipedia for some good ol' fashioned random web surfing. And though it may feel like procrastination at times, it's quite educational. In effect, it's like watching the Discovery chanel. You may be watching TV but you have become infinitely smarter than anyone who chose instead to watch reality TV.
After a stimulating conversation with my colleague, Bennett, my quest for today was to research Ray Kurzweil (you can find my annotations here). Ray is an interesting guy who wrote his first computer program at 15 (which was actually used by IBM). He's then had his hand in all sorts of different technologies ranging from OCR to speech synth to pattern recognition. He's widely regarded as a leading "futurist" and has a crazy dietary program to boot. Enjoy your procrastination!
