I think people can handle a simple series of instructions, like (1) download the Voyager for Lemmy app, (2) click the middle button, then click...
What they likely get confused about is the plethora of choices, especially when they aren't even sure that they want to join yet.
At the risk of bringing up unwanted drama, 100% of the time whenever I mention Lemmy to someone, they have admonished me for having done so. But putting myself into their shoes one day, I did a Google search (🤮) for "Lemmy", and aside from the singer, the top hit to an actual instance is... surprisingly to me, lemmy.ml. Next I note that the default search method there is "Local", not "All". NO WONDER they were telling me how politically "extremist" it (Lemmy) is! They see NONE of the posts from Lemmy.World, sh.itjust.works, etc., unless they are submitted to a community on lemmy.ml. Instead, what someone would see by default is "death to landlords" and all the other posts promoting the violent upheaval of Western society, as ofc capitalism is to blame for literally everything (well I mean...), except somehow only the Western variant is in the wrong and everything done by the likes of Russia or China or North Korea is absolutely fine.
Here's an old example I just happened to have handy:
(setting aside truth or falsehood, it definitely has a bias to it, as in both sides were equal, and yes this was prior to the USA election)
The #2 search result by DuckDuckGo btw is Lemmy.World (the #1 is ofc the musician:-), probably bc it has ~80% of all Lemmy users on it, so that is appropriate.
We need to put ourselves into their shoes, not our own as if we were ourselves on the other side of that conversation, but appreciate how they will approach the issues. And the methods used by more mainstream people differ from ours.
Either that, or accept that we are strictly another forum community used chiefly by Linux users, and that we will never be more than that.
