Because I still need it to access older repair guides and ask people on fixing stuff from cars and household things to study material and that community simply isn't as big here. I use lemmy with boost much more but I still use some services on reddit outside of that nothing else to do on there. So no need to judge, you are expecting a 5m community to have as much information and technical knowhow as a 150m user base. You can have a ferarri 458 you occasionally use when needed for the track ay and still daily a toyota prius.
