As with other things in the fediverse, discoverability is pretty ass. It’s a bit easier on Lemmy to find something you’re looking for than it is, say, to find interesting people to follow on mastodon, but it’s still not great. And often, you’ll find multiple communities on the same topic and you have to try to figure out which one looks like it will be better down the road (communities are still pretty dead and empty, so you can’t tell now which might be better). In addition to that, the interfaces for interacting with Lemmy are pretty rough at the moment, though that’s not surprising.
So do I like it? Enh… I’d say it’s a 4/10 right now with promise of getting better. Will it? Who knows?
I honestly couldn’t care less. Open source is not and never has been a differentiator for me when it comes to software, much less a requirement.
