Reddit didn't always have the user base it has now, it took them years to become big. I don't think we should strive to be as big as reddit.
I was reading the comments to a Lemmy post today (I cannot find it now, to link to it), where users who've been on the platform for a while talked about how the recent wave of signups improved the experience. If the people that are going to switch over at the end of the month continue to a positive influence, that's a win in my view.
