YC's goal in selecting Startup School participants is to get a mix of deeply technical people and popularizers. The combination of those two skill sets makes a great startup.
When I saw you at Startup School I was like, "Hey, it's cperciva! Maybe he'll find a co-founder who can sell and together they can make Tarsnap take over the backup business!" That would be a good thing for the universe.
Tarsnap is a great example of a better technology that should be backing up most of the world's data. It would, if you teamed up with the right popularizer to get the word out and close deals. It hurts me to see Tarsnap backing up only a tiny fraction of the world's data, while companies with great salespeople back up most of it badly.
Still, I think we delivered for some people who were inspired to bring their better technology out into the wide world.
Also: I hear you about power outlets. My current MBP runs Emacs for 8 hours so I've lost touch with that need, but I'll bring extension cords and power strips to future events.
