We've been holding a Twitter Space weekly on Mondays at 5p for about an hour. Even though it's not (yet?) a feature of Twitter Spaces, we have been recording them all; here is the recording for our Twitter Space for May 16th, 2022.
In addition to Bryan Cantrill and Adam Leventhal, our special guests on May 16th were Jordan Hendricks and Luqman Aden. Other speakers included jasonbking, Rick Altherr and Ben Kimock. (Did we miss your name and/or get it wrong? Drop a PR!)
