This seems like a interesting way to try to get the best use out of everyone’s time, for certain situations, the opposite of a deep dive:
The Ignite presentation format is a 5 minutes long presentation with 20 slides and with the slides advancing automatically every 15 seconds, forcing speakers to get the point, fast. It’s such a fast format that it’s best thought of as a performance, rather than a lecture.
(Not suggesting we use this within Tech Shed, unless someone specifically wants to try it. In particular, it demands a certain amount of preparation and rehearsal, and confidence, whereas we generally prefer something more relaxed and conversational, and with a low barrier to entry.)
Probably via the Long Now ignite talks.
