Some people might find the answer to be obvious (yes) but I’ve rarely found it so. In fact, this is a question I often find in the linux community (regarding linux going mainstream, not lemmy) and people are pretty split upon it.
On one hand, you may get benefits like more activity, more content, more people to interact with, a greater chance you’ll find someone to talk to on some specific subject.
On the other, you could run into an eternal September like reddit, where Lemmy would lose its culture, and have far more spam and moderation issues.
I don’t know, what do you think?
The great thing about Lemmy is that there’s no admin, no one site, no single set of rules everyone has to obey. So Lemmy becoming mainstream doesnt necessarily mean everyone tolerating a new culture. Niche communities can continue to exist, instances can isolate themselves if they want and turn off registrations, “eternal September” isn’t really possible on a network like this.
