In strict technical terms, yeah it's okay, albeit with the shortcomings to be expected of a smaller development team. In terms of population and activity with this format, I think it may be at the top compared to alternatives as well.
There's still others and other software options though for this format that people could try, which honestly may even be technically better, but lacking population/activity means they're in an odd spot.
The first of these you'll read about on here are likely Kbin/Mbin, possibly followed by PieFed or still-in-development Sublinks. Kbin/Mbin is definitely the runner-up in terms of federated Reddit-alternatives, as it was one of the few options available at the time people were leaving Reddit.
PieFed and Sublinks have emerged more recently with different priorities and approaches compared to Lemmy, but with the same desire to offer a federated option for people to deploy.
The last you may read about around here would be of stuff like Discuit, Lobste.rs, Raddle (and any other sites built with Postmill), Tildes, and the like, which are all most like Reddit in terms of their being stand-alone sites, unconnected to any others running the same underlying server software. However each of these, I think, may have lower population than the cumulative population of the Lemmy network of sites.
All that said, cutting to your last question: ultimately it heavily depends on the instance/site you settle into.
Lemmy isn't a monolith, which is both its greatest strength and weakness compared to Reddit. You may be able to find a Lemmy instance/site that heavily blocks out politics and moderates lightly, but the irony of this is that it means it may have to be overly-policed to achieve that, and might appear less active in the process from heavy disconnection/defederation from any instances/sites that permit political posts/discussion.
Right now though, much of Lemmy is heavily political, and it's arguably because of lax moderation to keep political posts/discussions to relevant communities, which is itself probably in part because of lacking moderation tools to enable lighter touches to redirect posts/discussions.
Nevertheless, it's possibly the best option fitting the format available at the moment given the rest, but if Lemmy and federation doesn't suit you you might check out Tildes or Discuit. Although be advised: Tildes remains invite only for now.
Links to all options/alternatives mentioned:
- Kbin, flagship site: Kbin Social
- Mbin. No flagship, check list of instances.
- PieFed, flagship site: PieFed Social
- Sublinks. No flagship, still in-development as drop-in replacement for Lemmy.
- Discuit. Not federated, but open source.
- Lobste.rs. Not federated, but open source. Requires invite.
- Raddle. Not federated, built on open source Postmill.
- Tildes. Not federated, but open source. Requires invite.
One last point, I swear, but if you do stick around and just want to chat about tv shows, movies, and music, I'd recommend visiting:
!moviesandtv@lemm.ee
!movies@lemm.ee
!music@lemmy.world
!casualconversation@lemm.ee
Honestly I think any general/casual discussion community would welcome posts about those subjects as well, which there are a number of across Lemmy sites to check out.
