I spoke with Seth Bush, who is organising his local neigbhorhood in Pennsylvania. It sounds like they’re having an awesome time at the hyper-local scale, creating more connections between neighbours and exchanging mutual aid.   
We talked about legal structures for collective finances, how to scale from one neighbourhood to many. We also talked about how microsolidarity is coming from a slightly different set of priorities compared to the main currents of the contemporary social justice movement.  
At the end of the convo, Seth gave me some great advice about how to be a better coach.   
Seth & I are mutual friends of Jonas Gröner, who I spoke with in a previous episode:  https://anchor.fm/Microsolidarity/episodes/Weaving-Social-Fabric-With-Climate-Justice-Activists-e1jnoei
