TL;DR: EA Global meetings have a default time, but you can skip to the goal of the meeting and avoid the urge to fill the entire allotted time.
I had a meeting with Lizka. It was 7 minutes. In the remaining time, we grabbed food, and decided to write this post together.
What was in our meeting?
Me: “How about adding [some mysterious feature] to nudge people to write summaries for their posts?”
Me: “We have time left, wanna write a post called EAG Meetings Can Be Short?”
Lizka: “Can we have an image in there?”
EAG meetings can be short, have images, meta jokes, and have a concrete result, such as something new posted to the Forum.
