Mastodon has benefitted from news articles and the sheer novelty of an alternative to Twitter, even before Elon Musk bought it out.
Lemmy probably won't have the same fanfare, especially given the stigma Reddit has, like it was a secret to have an account, or talking about it betrayed you as some weirdo or pervert. Whatever, Reddit never seemed to have the same social acceptance as Twitter or anything Facebook owns.
I think it is good to have a community that is self-filtering. Let's keep the IQ high on this one (with the exception of me, of course!).
Sounds like a cool future. I like it when my world expands.
