I used Lemmy for a while and enjoyed the technical-focused discussions (although they did not have the volume of reddit).

In the more general channels, it turns out I made a poor choice of host server, because it was still federated with lemmy.ml. Some specific hosts have historical revisionist tankie viewpoints and make deliberately bad faith contributions to discussions.

It was interesting to see this from tankies since I usually see such behavior from the far-right. But "North Korea is an ideal state" loses novelty quickly, so it became frustrating to read discussions.
