It was mostly what I wanted to say; I think I ended better than I started. My slides and script
with exactly what I planned to say are here:

Feel free to remix it. If I ever do another Ignite! talk (they're 5 minute talks with slides that auto-advance ever 15 seconds) I'll plan to say less, try to interact with the audience more, and may hire somebody (with bitcoins, of course) to replace my text-heavy slides with more pretty pictures.
