That's 9am-1pm in California, noon-4pm in New York, and 18h-22h in most of Europe.
The presentations will all be five-minute Ignite talks, apart from a short keynote TBA. We want to leave a lot of time and (virtual) space for side conversations, which was the biggest difficulty at Snap!Con 2020.
You're welcome to enroll (free, but you have to do it so we can plan based on the number of participants) and to propose lightning talks at snapcon.org. Please come!
