I get what you going to say but clapping with one hand just doesn’t work. I mainly go to soccer sub in Reddit and it’s easily over 20k people online at any given time. Here in soccer sub it’s only like 4k follower and daily active people of ~40people. No matter how hard I try to talk to it will be only to myself.

all the subreddits i love had no visible immigration to lemmy so i will have to wait a while to see the change

It’s not remotely easier. Trains carriages are easy to build, but the infrastructure is not. You have to move and extend roads, demolish buildings, lay the rails, build bridges, if you go underground there will be lots of digging and engineering work to protect nearby buildings, and don’t forget about maintenance. It is only profitable when the population is high enough and people have the need to travel to set places en mass. Otherwise it is just fantasy. If you live your whole live around any city Center, I can understand that you are not going to drive . But plenty of people lived in a tiny town of population under 10000people .

Just look at how popular threads is. Only a tiny group of privacy enthusiasts are truly worried about privacy. The general public in the whole world do not give a flying fuck.
