You can if you want, but Lemmy doesn’t translate them, like Mastodon does, and you might find them conflicting with the header Markup.
That, and Lemmy users used to a more Reddit-like structure of posting might get rather annoyed by it, since it would clog up the feed with unhelpful information.
The interfaces are better, and being able to integrate with mastodon is interesting.
The size of the communities, really. On Reddit, a lot of the subs have grown big enough that they can maintain themselves, whereas here, they’re pretty much dead without input. A few of the more interesting counterpart communities that I would frequent a tonne on Reddit are dead now, and if you’re just one user, it does feel like spam to try and contribute to it constantly.
It’s really only a limit subset of communities that seem very active at all, and they are generally news or politics based.
Bit of both. The culture in the larger communities would drift the way of Reddit just by volume, but the smaller ones are a bit more unique, and not always in a good way. Because Lemmy is a bit more tech-focused, I find a lot of the main medium-sized communities tend to have similar abrasiveness you see a bit in tech, though it can depend on both community and server.
