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.

it’s federated. It’s the only way it can work. Everything still on that ist must suffer from the same thing. Federation means handing stuff to someone else. Once that’s done, it’s out of your hands forever.
That cant be the issue because the site is called joinfediverse and everything it lists is federated.
