I'll sign up for Tilde the second someone can name me a platform that has out-lasted reddit, without selling customer data, and without being federated

I've yet to hear an example, and I have a functioning memory, and not eager to keep repeating this same cycle.

It's like password managers. Every few years the current popular one has a misstep and everyone flocks to the next closed source, for-profit alternative. Meanwhile I've been using "pass" for over a decade. Do we think it took me longer to learn pass, or longer for folks to migrate hundreds of passwords multiple times?

Being an invite-only alpha kills Tildes for me, even though I’m interested in it. It seems the closest to what I want out of a Reddit alternative.

I would hope the community would understand outages, bugs, and oddities if they made Tilde an open alpha.

I love reading Tildes, it's great. It reminds me of reddit back when they started, and of HN: interesting discussion without jokes and puns destroying the discourse on the site. I find a similar quality of discourse on https://themotte.org as well, even if the topics are a bit more politically charges, sometimes.
