It's not necessary for me to disconnect. It's just that I'm doing a very long, slow wrap-up on my most recent online project and presence. Maybe there'll be another. I'm poking around to see, because this isn't the justly lamented '90s Internet anymore and it's now hard to locate online places to settle that aren't hostage to a corrupted oligarchic establishment.
Not a Bitcoiner. I will never be a Bitcoiner, or at least I will never admit to it, because, with my philosophy, naturally I will never willingly write anything that must ultimately attach my mundane name to an uneditable public ledger. This makes nostr an awkward fit in some ways. But it's not obviously unworkable.
What I most regret, over the decades, is some of the unintended disconnections from people I liked. When the common activity ended, we exchanged contact info and went our separate ways for a while ... and, eventually, even with people who don't intentionally fade from public view as I do, the contact info no longer works. I should have acted more quickly to keep those contacts live. But I didn't foresee the ephemerality of life online, back then.
