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.

I’ve said it before, but I joined this instance when Reddit closed the api and the only time I see “tankie” stuff is when someone mentions how rampant it is on this instance, but not on the instance itself. I guess I subscribe to non-tankie content (all across the fediverse and not only this instance).
