I have never understood why so many people find the structure of Twitter/Mastodon more appealing than that of Reddit/Lemmy.
I like it when I read other people's thoughts on a matter, then react to them by adding relevant thoughts of my own and hoping people will react to mine too. Like on a traditional discussion forum (or for even older people, newsgroup or mailing list). That is what Reddit/Lemmy does reasonably well, although not quite as well as those traditional discussion forums.
On Twitter/Mastodon I have to have original thoughts of my own to be able to post anything at all, and even if I do have some, no one will read them if they aren't already following me.
