If you've never heard of the movie or TV show, Buffy the Vampire Slayer, the name Joss Whedon will likely mean little to you. But then, so will the word "Internet." A couple of years ago, Whedon assembled some friends, including Neil Patrick Harris of How I Met Your Mother, and made a three-part web-based series, available to watch online, download from iTunes, and finally on DVD. It was hugely successful among nerds and geeks. It was called Dr. Horrible's Sing-Along Blog, and this is some of the wisdom we can glean from Dr. Horrible, himself.
