We had the same thought. Right before I saw your reply, I added some hobby communities to my comment as examples.
This place is so flooded with politics and raging over the news that I’m about to choose a random hobby community that’s active and pick up said hobby just to be able to have something besides Star Trek and Linux to talk about here lol.

























Look at it from a new user’s perspective; someone who has not curated their feed or otherwise “made the fediverse what they want” yet. e.g. They land on Lemmy World or another big instance and their default sort is “active”. Doing that now in an incognito window, and half the front page is rage, same on the second, and the stuff that’s not are some random shitposts and Linux filling in.
Truth be told, looking at that, I probably wouldn’t want to sign up. Especially if I didn’t know that different instances have different cultures, etc.
Assuming they’re a normie (which we desperately fucking need here), I just don’t see that they’d want to stick around. Aside from trolls and spammers, the only people we seem to consistently attract here are the “Wah wah I was banned from Reddit” types and, while there’s certainly a sizable pool to draw from, I wouldn’t exactly consider them the pick of the litter for growing the fediverse.
The point of OPs post is that usage here is declining, and I am simply pointing out that I feel all the rage and politics is not particularly inviting.
Edit: And you know what? I’m just going to fucking say it. There’s too many armchair activists here who won’t let you enjoy a single moment without reminding you that something bad is happening somewhere in the world and that you have some kind of moral obligation to be angry all the time about it. And if you’re not angry all the time then you’re somehow part of the problem.
