jointhefediverse.net seems to be a commonly linked resource for directing people to join the Fediverse.
Curiously, it does not list Lemmy under the list of Reddit alternatives. Their GitHub README explains why.

Lemmy.world has literal propaganda, too.
They posted a Radio Free Asia article and banned anyone who pointed out it’s a government run CIA propaganda op. Even redditors know that’s propaganda lol.
It’s everywhere, you can’t avoid it, you just have to learn to be discerning, media critical, and look into sources.
