The "front page" of lemmy, either the local of the instance you're on or the "all", is pretty bad. Low quality, uninteresting, obscure, sometimes vaguely rude. News about small video games, hyper specific gripes, obscure memes, uninteresting articles with no comments. Compare that to reddit when it was good, which reliably emphasized the biggest world news stories, genuinely interesting user anecdotes or personal stories, academic knowledge (especially AskHistorians), videos or images that grip you, etc. I'm not sure what the issue is with lemmy's front page. Is it an algorithm problem? Something to do with federation? Is the user base merely too small for now and this will improve on its own with more engagement?
It's too bad because the "front page" is the user's first taste of lemmy. Most users will browse without making an account for a while before finally making an account and subscribing to specific communities.
In general, I think lemmy is already great. There are starting to be lots of cool communities, and even if the quantity is lower, the quality seems to be higher.
The front page of Reddit is one of the places I’ve actively avoided. That’s the place where I’ll find everything that the rest of the world likes to see, but none of the stuff that I care about. I tend to be interested in strange niche topics, and my multireddits reflected that quite clearly. To me, the front page of Lemmy is about as boring as the front page of Reddit, so no big changes there.
