I love this idea and think we definitely should. We’re gonna learn a lot about what works in terms of engaging communities in-real-time through our Local Ambassador pilot campaigns soon so we can come back with best-practices and learnings from that to inform a more (global?!) version of what you’re talking about here.
Also paging @gua742 to share how successful his timed “shouts” in the Seattle area have been? I know he’s building a real community out there already!
