Improve synchronization

I get the impression we could use less time and energy to synchronize. Possible things:

• 'collective work week', limit collective activities (CoMe, roadmaps, etc) to a certain part of the week
• 'good times survey', ask people about preferred times for e.g. meals, meetings, celebrations, etc. to use to set up...
• 'default times', to create a bit more regularity and help people plan cooking, working, etc
• 'aggressive calendar promotion', e.g. going around, installing DAVdroid on peoples phones, telling people off for not using it, etc
• 'e-cal', install a small monitor with calendar somewhere
• revise CoMe sections/flow (as ever huh)

DoD: explicit change(s) + collective perception of improvement
