Agree. I have curated my follows/groups so that I generally don't see a lot of crypto or gaming content, because it's not really my interest for the most part. I follow a couple of people who post about crypto to keep abreast of the news, but other than that, not really. But whenever I go to a general trending page or the latest posts on 3Speak, it's like 90% crypto and gaming. The thing is, that's what people are going to see if they just come visit Hive for the first time - and if that's what I had seen, I probably wouldn't have joined way back on The Other Blockchain. Luckily I had a friend on here and so I started checking out things via the tags instead of the trending page and stayed. But I think it's probably a self-perpetuating cycle; people see that when they first join, and if they like that, they stay and participate in that, and unless they're guided in by an extant user who does other things, all the other people probably go, "Oh, nah" and don't join.
My main blog (this one) is a mishmash of all sorts of stuff, and my second is stop-motion faerie videos (@faeriestories), and granted, part of it is because I tend to socialize on main so people don't see my alt around very much, but whenever people discover my faerie videos, I almost always get surprised reactions like "This is on Hive? I never see stuff like this on Hive, I had no idea" because you gotta LOOK for different content.
