The big thing with any Reddit alternative is what kind of community is migrating over there. A lot of controversies Reddit has had in the past have centered around vocally discriminatory communities migrating to a new platform after Reddit has decided their content does not align with their views and goals as a company.

Fatpeoplehate, the_donald, probably jailbait I imagine (though before my time on the site thankfully).

The one exception I would say would be the uncerwmonious firing of Victoria from AMA which caused an uproar and led to AMA's never really feeling the same. I didn't think about leaving then, but I understood the anger and concept of reddit slowly losing its identity in favour of a more corporate one. Ironically Reddit's latest decision has led to AMA opening the flood gates to anyone and everyone, giving a more genuine feel to the community.

Now 3rd party apps being shut down (although revanced provides an alternative) has caused a general consensus it's time to leave, fragmenting communities into different websites and platforms. I've encountered some hostility and opinions I personally disagree with on Lemmy, but overall the generalized community here is a good replacement, over a displeased and spiteful group that would fixate on one specific person or upset over one specific group of people. Perhaps thats just the nature of the fediverse overall where - if an admin of lemmy.ca decides to make us a proudboys affiliated network - I can just go elsewhere.

TL;DR Lemmy is all I need. It's not voat, it can federate with kbin fine, and it's open allowing anyone and everyone to have their say. I like Lemmy!
