I quote the lawyers: “it depends.” Are you here for a more personal community? Do you love endless masses of discussion? I’m sure there more questions to go along with this.
For me as well, I never really participated much in Reddit due to the sheer size of most discussions. I do enjoy being able to make a comment that isn’t washed into the void instantly, but I don’t know how much that would actually be affected my Threads. There’s a chance that the majority of Threads folks won’t even bat an eye at the rest of the Fediverse.
What I’m more worried about is the fact that this is a massive, for profit, information harvesting corporation is trying to squeeze themselves into a five times smaller system. Why not start their own thing? They hyped up the Metaverse before, why not build off that?
I conclude that they see a way to maximize profits by setting up here. Be it as innocent as that they hope for more traffic from the Fediverse or something like hoping to snuff out competitors, I don’t trust it. On the same level as I don’t trust them with my data.
