What is Five Minutes of Fame?

Five Minutes of Fame (5MoF) is ten five minute talks in an hour, with a short intermission so you can get another beer. Talks tend to be ad-hoc, poorly-planned, and awe-inspiring.

How do I sign up to give a talk?

Sign up to speak by following the link above, clicking "edit", and adding yourself to the list.

When and Where?

5MoF happens at Noisebridge, 2169 Mission St, San Francisco every 3rd Thursday of the month at 8pm.
