I run a few groups, like @fediversenews@venera.social, mostly on Friendica. It’s okay, but Friendica resembles Facebook Groups more than Reddit. I also like the moderation options that Lemmy has.
Currently, I’m testing jerboa, which is an Android client for Lemmy. It’s in alpha, has a few hiccups, but it’s coming along nicely.
Personally, I hope the #RedditMigration spurs adoption of more Fediverse server software. And I hope Mastodon users continue to interact with Lemmy and Kbin.
All that said, as a mod of a Reddit community (r/Sizz) I somewhat regret giving Reddit all that content. They have nerve charging so much for API access!
Hopefully, we can build a better version of social media that focuses on protocols, not platforms.
My experience has been that the “Hot” view is most similar to Reddit if you’re looking for new content. You can read about the different sorting here: https://join-lemmy.org/docs/en/users/03-votes-and-ranking.html
What I’ve noticed about the “Active” sort is that older posts that are still getting upvotes and have new comments can remain at/near the top of the list for several days. I think this is good if you want to see where ongoing discussions are happening. On Reddit, I often felt that an interesting post fell off my view very quickly. I know I wasn’t the only one, which is probably why people would post a “remind me” post or “following” post on Reddit so they could come back to it later. Regardless, someone might entirely miss a post that blows up in a community but sees it in the “Active” view and check it out. I like “Hot” because I can see what’s trending up, but I frequently switch between Hot and Active. I’ve noticed that many of the “hot” posts don’t have any comments.
I agree with you regarding quieter communities. Reddit had something in its sauce that allowed posts from less active communities to show up in my feed through all the noise of busier communities. This didn’t happen for all the subreddits that I joined, but rather, the ones I showed an interest in. The downside of that kind of algorithm is it reinforces the echo chamber effect as the algorithm is learning what I like and then showing me more of what I like to get me to stick around longer. This system isn’t (currently) prone to that kind of manipulation.
I would like a “rising” option, one that is more a mix between New and Hot bacon reader for reddit does it very well.
Active has a 48-hour cut-off, and the ranking function it uses seems to encourage the same few posts to stay at the top for 48 hours. It’s basically the same ranking as “Hot”, but using the timestamp of the last comment instead of the time of posting to decay its ranking over time.
This means any comment activity whatsoever on a popular thread bumps it back up the rankings significantly, and I suspect leads to a kind of snowballing effect that keeps posts higher up. Ideally, it would use some metric based on user interactions over a time period to calculate a score of activity rather than solely the latest comment. In effect, it seems to act more like a “top from last 48 hours”. (Although I would add I’m a newbie to Lemmy, so might not yet have an accurate picture of its behaviour).
Lemmy seemed to get much livelier for me when I switched my default to Hot, but I wish there was a way to disable the auto-updates (I’d rather see new items only on browser refresh). Active sort feels pretty stale to me.
