I like this about Lemmy too, I am also guilty of one liners as I have also made them, but I try not to in a serious discussion. In reddit if you take a highly upvoted post most often the top comment would be some joke and the follow ups are riding that joke, even if someone makes some good well thought out comment, the following comment seems jokes or one liners picking on the comment. Good comments gets buried underneath all the trash comments and it feel like a chore digging through those comments to find some meaningful comment. I understand when this happens in meme/shit posts but when it happens in tech or serious post i get pissed.
I knew about Lemmy 3 years ago and joined lemmy during the api bullshit about 2 years ago. After that, I had my time where I went back to reddit ocassionally as initially I felt there were way less content on Lemmy, but every time I went back I just couldn't get along with reddit, even though the content was high lot of it were just trash and the comments weren't engaging and mostly toxic or circle-jerking. I am glad that I am now settled in Lemmy and have now limited reddit to only finding answers to obscure tech problems.
