Lemmy felt very unique, very different from the other softwares we tried, and very fitting for conversation. (Probably, it's the other way round: The community and the needs of the community grew around the software (then reddit), and the usage which worked best was the one which stayed in use...)
I had a lot of fun on lemmy, and I might continue using it! I started a Nomic community and will play a little over there. Feel free to join, even if you don't know Nomic yet – the rules are self-explanatory (but not in a good way :D).
If you would want reddit, you might not find exactly what you want. The community is different and smaller. But if you want Star Trek memes and politics, you might find interesting discussions. As far as I can tell, the inner workings are mostly copied, but I was never on reddit, so maybe that's something for the comments.
There are a lot of memes, which got me very easily distracted. The default view is "every community on this instance" and not "the communities you have subscribed to", which was a little annoying, but okay.
It actually federates quite well. You can follow users and even communities (the lemmy equivalent of subreddits afaik). To follow a lemmy community from mastodon, put the URL of the community (e.g. https://feddit.de/c/nomic ) into the search bar of your mastodon instance, as shown in the screenshot.
Another problem was that sometimes I couldn't post my posts, I just got stuck in a reloading state... I'm not sure if it's a problem of my server or the software as a whole. @blinry had the same problem.
