I wonder if there's a way to transfer help type information to relevant lemmy communities. Something that the search engines can pick up to direct more people towards lemmy.
No, nobody owes you anything. Start putting info into documentation and issue trackers and leave social media to be the brain rotting dopamine treadmill it became. If you need technical information, go into the official forum, discord (ew) or IRC channel of the project and ask the people actually using and developing the tech there.
