where are the people taking action? sincere question…
Less connected, more IRL. Depending on your interests you will find them in farming coops, fablabs, citizens groups...
You could read the classic Hakim Bey's essay on TAZ (temporary autonomous zones) to understand why real life experiments are not very advertised. Tl;dr: many are fragile and can be killed by success/attention. When you have to do a bit of effort to reach them, it creates a natural filter of motivation that guarantees that the people who come are those who will contribute, not just mere tourists.
