I joined because Reddit has become a cesspool of bots and toxic behaviour. Lemmy is still completely open-sourced, while Reddit isn’t at all now. Also, when you first sign up on Reddit currently, you get completely ignored now and can’t post or comment on regular subs.
I understand that, meaning what made you join the community, if you will.
I try to join all of the fediverse services to give em a fair shake. I haven’t tried Helos yet, and I can’t get into the wanderer instance I’m most interested in, but I’ve tried all the big ones: mastodon, loops, pixelfed, bookwyrm, funkwhale, etc. I’m a social media nerd so I like to stay up-to-date on what folks are doing in the space, and the fediverse is the one that most closely aligns with my values.
