Just wanted to weigh in so you guys can stop second-guessing me
I'm not interested in the drama associated with running a co-living house or in being the mayor of a small village fort or a bunch of cohousing units. This forum has enough drama for me already.
Space is indeed the limiter on social behavior. ERE people live too far apart to gather spontaneously, so meetups have to be arranged well in advance and time-slotted so people can drive/travel the required 1-5 hours it takes to get here. Space prevents "members" from interacting spontaneously and so connections remain shallow. Even Chicago has this problem as it can easily take an hour to get from one end of the city to the other. Even with the luxury of time (that salaried people lack) two+ hours is a big barrier to overcome.
Cohousing corresponds to an IRL version of a chatroom. (asynchronous)
A ERE meetup corresponds to a zoom meetup. (synchronous)
People living within spontaneous walkable distance of each other corresponds to this forum.
Others have made the "within walkable distance" work by picking a location and moving there. Presume that presenting such an idea to 10,000 people might get 10 or so people who are interested and 1-2 who are more than interested. However, for ERE there are simply not enough of us to get this started unless the percentages are higher for ERE than others... and I don't think they are.
The "Learning Tribe" was intended as a regular ERE meetup with repeat visitors that went beyond the "introduction, dreams, and progress so far" with first-time visitors that usually dominate ERE meetups. Covering some project was meant to be the carrot that made people come back.
In particular, given the numbers and given my lack of interest in being the trailblazer of social organizing, it would be more effective/practical for me to seek out other communities I might fit into than to seek out individuals that might fit into my/ERE community.
