It used to just be a regular forum for people to post and discuss. It was special because of the upvote/downvote karma system. The user count got money hungry people’s attention, it went corporate and it became a place to take in revenue.
Now people have learned from it, and used it to create their own forums based on the structure of Reddit.
The thing that made Reddit special was it was everything you wanted all in one place, instead of having multiple forums on multiple different websites for multiple different interests, it was all on Reddit.
Now we have the fediverse, it’s multiple different websites, that follow the same principles, and they all work harmoniously with one another.
Just like nature finds a way, genuine humanity finds way too, even on the internet.
