Totally agree about the community feel. I used to spend a lot of time on Usenet in the late 90s, early 00s, and to me the #indieweb movement reminds me of the kind of connections I made there. Lose relations, tightly coupled to an idea or a theme. I used to participate in a Danish usenet group for Macintosh/Apple heads. It was great, met a lot of people IRL, some I still have occasional contact with today.
