Yes, but quality over quantity. I was a redditor back in the early days, pre Digg migration. Being a redditor meant something back then, almost universally meant you were tolerant, usually but not always somewhat liberal, and with a very strong sense of fairness. I remember a good friend of mine started dating someone and when they mention their new partner was a redditor I am immediately thought oh good, that means they are very likely a good person (they ended up married). Reddit has of course grown since then, but not all of the growth is good. I used to go there for engaging discourse, knowing that I was surrounded by other relatively smart people and we could have respectful discussion on almost any subject. Those discussions are few and far between now.
So yes I would like Lenny and the fediverse to grow, but I am more interested in what kind of people we attract than simply growing numbers. When I would rather do is create a reputation that the fediverse is a place to come before respectful discourse and sharing of ideas, not just scrolling through page after page of mindless content like on a big tech social platform (FB / Insta / TikTok / etc).
