Leaving Twitter for Mastodon was very easy. I pretty much left and never looked back.
Leaving Reddit for Lemmy is not easy. Been in the process for a couple of weeks and I still find myself spending hours on Reddit and very little on Lemmy.
I had the opposite experience. The ability to watch feeds of interesting people on mastodon over Twitter was completely lost. The instance I joined was so quiet. I kind of just gave up.
Lemmy is like lightweight Reddit and the federation seems to work out of the box unlike mastodon. It’s nice to see posts from various instances without having to do much.
Yeah well in my switch from Twitter to Mastodon I also changed how I used it. On Twitter I followed a bunch of people, and many related to politics. I didn't want any of that on Mastodon so I started focusing on following hashtags instead, which I found a much better fit for me. I follow some people, but I get more content from the hashtags.
I agree on the federation on Lemmy, it seems pretty functional. But I get like a fraction of a fraction of a fraction of content on Lemmy compared to Reddit. But in a way that's good, because I spent waaaaay too much time on Reddit.
