Ask HN: What does a job-seeking start-up developer use for a "resume" today?

I've always spent immense amounts of time on my resume, perfecting every line and making it look nice and crisp on one page. But I've always had my resume geared towards big business and government, since that's where I've generally worked. All of my programming work has been for myself or freelance, where I could simply show a project portfolio and didn't need to have a formal resume on hand.

Thinking about getting a job at a start-up instead of continuing work on my own, I realized that I don't know what passes for a resume these days in start-up-land. Is a formal, crisp one-pager still required? Is it Linkedin? Do I simply send over my Github profile? Is it basically a requirement to keep a blog now and self-promote?

The question arises from the fact that all of my programming expertise was outside the context of a formal job, so my one-page resume doesn't tell the "developer" story you'd expect. On the otherhand, my Github isn't standalone, since most of the work I've done as been closed-source for clients.

What do you think? Could you provide examples of what you've seen or what you give out? Do you even use a resume?
