My experience with the Fediverse has only been through Mastodon, through which I struggled to find a community I really gelled with. Either it was supper overwhelming with meme posts or NSFW, or it was too chill to the point of nothing. Or, it was hyperfocused like FOSS/Linux and became uninteresting after awhile. May try again, but I think I will explore the other fedisites like Plemora or Calckey to see if I like it better.
I love the pace of a forum. I grew up primarily with GameFAQS and some lucid dreaming forum, and honestly it was very formative in teaching me how to write and use critical thinking skills, as well as how to respond to a variety of temperaments. I stopped participating in online forums awhile ago, and while I loved Reddit as a resource, I never felt inspired to participate. In the same way, there are an incredible number of forums dedicated to a certain topic, and are extremely valuable, it would be annoying to make an account for all the things I am interested in.
I like what lemmy is becoming. Glad to find system that makes interacting with people enjoyable.
I think the main difference comes down to the sorting algorithms. In Lemmy we get the organic content sorting done by collective human appreciation or lack thereof of said content (↑, ↓). Generally better stuff rises to the top, and worse stuff sinks to the bottom. You can still see either if you like by changing the order. That coupled with sorting by community does a great job at sifting through the noise. In Mastodon you have hashtags that can serve as communities but there’s no organic sorting within that. If you subscribe to #Linux, you’ll get pretty much everything with #Linux, whether one or a thousand people found it valuable.
