I started to ween myself off when they announced they were killing third party apps since I was never going to use that trash app. As the weeks went on and they showed they would rather prioritize their interests over the community I realized things would never change and the idea of what reddit was in my head didn't match reality so I made a few Lemmy accounts.

There are a few niche subreddits that didn't come over or I just haven't found them, honestly I've not really looked. It took a bit to acclimate to Lemmy and how things federate and there were a few syncing issues that were fixed pretty quickly as the exodus happened which is really nice. The admins on all the instances seem to have their own biases in how they run their community and those seem to fall in line with the rest of their communities so it doesn't seem like a big deal as most recognize their differences and try and work together anyway. I think that even though some may disagree or outright hate each other they want the concept of the fediverse to work so they put in the effort which is all anyone can ask of each other.

As for how I'm doing and the fear of missing out, it's honestly not much different other than a few niche communities that are available off of reddit anyway so I don't feel like I'm missing out on anything. The only thing we don't have is a fediverse mascot afaik.
