When did you last sit down and have dinner with your next-door neighbor? Discuss the local happenings and politics of the neighborhood in person?
You might be able to answer that question in the affirmative. But many more don't. We're too busy isolating ourselves from one another to grow any form of culture from which organized efforts would spring.
Many places still sort of exist through stuff like farmer's markets, some clubs, libraries, swap meets, etc, but they seem less generalized for socializing.
I haven't met with my neighbors or sat down to chat with them. It does feel kind of alien and, dare I say it, rude to intrude on someone's life that way. Maybe it's not really an intrusion, and an atmosphere of fear and distrust has trained us to separate. I remember my parents meeting people and scheduling times to hang out all the time. Children from different families would mingle while the adults mingled, everyone got some dose of community.
I couldn't tell you where programming hobbyists meet up in my area. I might have to go up to Tacoma before I find any no-or-low-cost hacker groups. But, don't many communities also have common places they go routinely? I'm thinking gaming and TTRPG, TCG shops might be a good start to build a third place, despite being a business themselves.
