I've been hanging around without doing very much, so far.
Motive for being here at all: escaping the Censors of the Left, and the Censors of the Establishment. _My_ Internet, the one that I joined in the 1990s, is dead and gone, partly through the usual course of eventual concentration of corporate power, and partly through the malice of powerful people who freaked out at the intolerable spectacle of mere plebeians daring to say unapproved things to large groups, in ways the powerful people couldn't (then) readily control.
I can cope with a lot of Bitcoin posts, but I never propose to join the congregation of Bitcoiners, nor to post about Bitcoin.
I rather like the homesteaders and do-it-yourselfers but, for various reasons, will probably never have anything useful to say there either, since I can't follow that path.
If I go forward, that means bootstrapping a community that discusses other subjects I'm interested in. Starting from scratch means:
1. Committing to post on the subject most days; and
2. Making the content publically available, but concentrated in one findable place, so it's possible to recruit non-nostriches by saying "if you're interested in Y, sign up for nostr and do such-and-such";
3. Some mechanism of pest control. A small enough group can get along without it for a while, being scarcely noticed; a successful group will eventually need it.
1. is personal: it means finding the free time and dedication.
2. & 3. are questions about what's technically doable with nostr, and how? which I have not yet adequately researched.
