Why does the frontpage of kbin.social work so much better than any other server?
When I visit kbin.social, I see new posts regularly. On other servers posts stay on the frontpage for multiple days. This is also true if I switch their sorting to "hot". So that is probably not the difference.
I presume you're talking about Lemmy from any of the different instances. If you're looking at local it's only going to show local posts and not "everywhere". Be warned though, currently there's a bug where when you do select "All" it updates with a pull from outside the instance very often, so much so that it can make reading and browsing difficult. That should be updated soon.
I mainly tried lemmy.world, lemmy.ml, beehaw.org and a few others. I did try them with and without "all" and it was cumbersome regardless. Either I was served posts with zero or negative upvotes that to me do not classify as "hot" or my feed did not update at all.
What's weird to me is that kbin.social was the only one I tried that was not affect by any of this strangeness.
Kbin and Lemmy are different frameworks and have been written using different languages. After some hiccups initially, kbin seem to be more stable than Lemmy right now, including when it comes to frontpage sorting. But both are pretty new and are actively being developed. You can expect these issues to be fixed soon as the devs push new updates.
I've seen like 5 different posts about this already, I guess I'll reply to this one too xD
Lemmy "Hot" ranking is currently kinda broken. There's an edge case that stops the hot_rank column from decreasing, meaning the post never goes off the front page. Will be fixed in 0.18.
More in-depth answer: Currently there's no set date. It depends on how quickly they can tear out all the WebSockets code and replace it with simple HTTP (that's the BIG change, will fix a lot of different things), and then test those changes. The hot_rank fix has already been merged, that's done, but they want a stable, cohesive release with all the good stuff.
Current estimations I've seen range from 1-2 weeks, but it all depends on how fast they can get it coded and tested.
