- office hours: this is not a meeting ... it’s just a team dialed into a hangout or other voice chat for an hour. Totally optional. Folks can talk while working, talk about work, talk about not work, whatever. Just share the virtual space for a bit. This can be really helpful for “serendipity”, building trust and depth in interpersonal communication, cross-training, and otherwise just de-tensioning if you are involved in a high-stakes activity.
- BOF/hack-a-thon/quarterly on-site... basically, everyone meets somewhere in meatspace for a week (Monday PM to Friday AM). Good things to do during this time: planning, team-building, demos, tech-talks, bring in an outsider or trainer, etc. Lots of larger OSS projects do this.
