If you really want people to join the Fediverse, or install Linux, or whatever, don't yell at them (it dosn't help) -- adopt them.

Offer meaningful, on-call (tech) support to someone to tackle the project of your choice. Stay available/involved until they truly find their way. Then take on more people as your capacity allows.

Also look at how this concept applies to non-tech needs in your community, too. Interesting.

It's the difference between bullying or grandstanding versus helping.
