Sure. For me it's the other way around. I've never really fell in love with microblogging. My hobbies are kind of mixed and sometimes niche, I sometimes don't have anything of substance to post from my everyday-life and I really disliked the mob mentality and regularly surfacing toxicity in places like Twitter. And at some time I tried Reddit and got hooked. It's a very different approach whether you follow people or topics/communities. It's less about who you are, but more a marketplace of ideas. A level playing field. Sorted by ideas and hobbies and you can just dip in. It also makes you target different audiences for different niche hobbies. And everything gets ordered like that. I mean you also have hashtags on Mastodon, but it's not really designed around this concept.
It really has some appeal to me. I also sometimes participate in web forums and found a similar structure in this. And I always liked how the free software community is supposed to work. It doesn't matter who you are, if you're 15 or a 40 yo woman... You just all come to the same place and discuss your ideas and perspective on things.
It does have downsides. And it doesn't necessarily foster good behaviour and being nice to people. I don't have an ultimate opinion on this. I think encouraging good behaviour in discussions, requires some degree of 'it matters who you are'. Because having an image stick to you incentivizes you to behave properly. It's not than big of an issue in practice, the overwhelming majority of people is nice and they use the platforms to everyone's benefit and not to troll and cause trouble.
Thanks for your input. I've come to the conclusion that maybe I need to broaden my perspective. Have a closer look at other places in the Fediverse. I'm pretty sure Mastodon ain't it for me. But Friendica might be a good place to start. I've also had Akkoma reccomended to me in this discussion. Maybe some other software than Lemmy is more closely aligned to my vision of what I'd like to run on my server. I'd like to stay compatible with Lemmy, since there are lots of nice people here and it's usually fun to talk here, more so than in some other places.
