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 has mbin and piefed on the list, so it’s not harming the network at all. If anything it’s more healthy with more platforms rather than just ml and world. It’s one site directing people to the fedi, I’m not butthurt about it
