Even if that's true, which I'm not seeing from a cursory glance; they've released their project as open source and it seems active.

They've chosen technology I like too (python/postgres/redis/saltstack), and it seems to have a clean interface.

On purely technical/product merits I like it.

There's only one admin, and he's literally never posted an alt-right opinion in my entire time on the site.

You've been terribly misinformed, and now you're misinforming others.

Maybe mistaking it for voates?

That's a heck of a site to mix it up with if so. Their philosophies could not be more opposite.

I believe you might be confusing it with Voat.

The alt-right, despite all its flaws, so make very good open source forum software

Any sources on that? Tildes is a young community still tho, voat failed and I don't think it'll be able to reach much success either (where success = massive volume of users). We'll see.

Did Voat fail? It seems to me they attracted precisely the demographic they intended to.

Yeah, they have no posts in months? Or am I missing something
