LAST SUNDAY, I walked into the business heart of San Francisco, tapped on the closed offices of a profitable IT business, scooted into what looked like their main conference room, sat down, and started fixing bugs. I felt a little like an accountant breaking into someone’s ledgers at night, and double-checking their book-keeping.

I was there for the “Twisted Sprint”, which is perhaps both slightly less fun and/or painful than it sounds.

But it was certainly enjoyable enough for me to sit there, working for no pay on my weekend at something – programming, bug fixing, documenting – that others get paid a lot more than I do to do full time.
