The specific point for me was the attacks on @christianselig@mastodon.social from that dumpster fire of a website.
I had been looking at Mastodon since @deviantollam@defcon.social spoke so highly of it and the platform it provides for marginalised groups but personally dislike the microblogging format, and when looking for Reddit alternatives it seemed like Lemmy would be a catch all for me. Looking forward to the integration getting tighter to expand discussions across the fediverse.
