Seems pretty even to me:

(Should not look at created accounts, those are spammers)

Probably because of the endorsement of Lemmy by subreddits, which has been far greater than the endorsement of Kbin. Lemmy's also just been around far longer than Kbin. Those server issues that Kbin encountered during the whole explosion of users also likely slowed down growth a bit. Even with Lemmy's bot problem I think these have made it grow faster anyway.

@BananaTrifleViolin. I'm fine with it. I tried lemmy first and was met by a ton of issues from the influx. Kbin thus far has seemed more stable and honestly I like the layout a bit better.

I admit that I had buyer's remorse for a bit after immediately jumping to Kbin and finding out later that Lemmy existed. Lemmy's UI just looks friendlier and more colorful. But I'm sticking with Kbin-- no reason not to, really, since all (or most) of the content cross-pollenates!

Kbin is growing faster than Lemmy. Lemmy just saw a huge amount of spambot registrations recently.

Lotta bots on Lemmy. The stats I saw looked like 200k users in the last few weeks. I'd willing to gamble most are bots. Maybe some for ads, maybe some to claim names then sell 'em later.

Most people heard about Lemmy on reddit, and heard about kbin on lemmy, possibly after they already made an account.

Im not going to not interact with Lemmy because of its developers but it was enough I decided id rather not be tied exclusively to their tankie ass politics.

I think a lot of people moved from Reddit to Kbin in the early days of the black out and at that point Kbin was isolated from Lemmy. So when people saw less content they jumped to Lemmy. Which just made that already big community grow. Then people told other people they went to Lemmy instead of Kbin.

Fediverse is fediverse

Some of that may well be real, but one issue that is a factor is that it appears that someone is having bots auto-creating accounts at lemmy instances with open-sign-up, which is believed to be responsible for a considerable portion of the new accounts (basically, many of the accounts don't appear to be active, and apparently the instance admins are banning a number of them). The lemmy.dbzer0.com instance admin has something up on GitHub to try to monitor the situation:

I'll add that that does highlight the fact that the Reddit team has put a lot of time over the years into countering bad actors, spammers and the like, and some of those are probably going to try to hit lemmy/kbin.

Lemmy is having a lot of bot issues. I think once they get that sorted we can get a better comparison.

All I know is i’m using an ipad and everytime I try to log into lemmy i’m stuck at the login screen with a spinning icon. Tried kbin and it just works, no hassle.

I have signed up for both in the past 24 hours. I think there are pros and cons to both and honestly I like both about equally

Most people like me came to lemmy when they first left reddit and it was just there. my first instance was lemmy.ml and they where having issues so i went to lemmy.world and it was amazing. i kept hearing about kbin but they where having issues also. eventually kbin was stable and now i'm here for the long haul. lemmy has basic features like subs and you can subscribe and create post etc.. kbin has Threads = Reddit Post, Microblogging = Twitter and Magazines = Subreddits all in one service. Make an account and see for yourself. you can have a lemmy account kbin dosen't matter!

I have been using Lemmy initially, but have switched over to trying Kbin. I am still unsure which I will use mainly.

I think Kbin has a much cleaner UI, but I think I like the process of commenting on Lemmy much better. Many little things, like having a "top" sort option to see the top comment, and comment box under the story as opposed to at the bottom of the page. Also, you can minimize comment trees in Lemmy, which is a necessity.

Lemmy's one big issue right now is its main page sorting is broken and needs desperately to be fixed.

The magazine from the federated server may be incomplete. Browse more on the original instance.

that's a big part of it. people want something that just works, and they don't want to leave the site to see the latest submissions/comments.

Some Lemmy instances don't have any sort of validation on user signup, but Kbin absolutely has user signup validation, which limits how fast we can grow(and is a great thing IMO).

Also, with the way federation works its almost a benefit since then kbin(and any other smaller server) can maintain a tighter community with the ability to cut out servers with negative experiences(read: too spammy/too many bots/too hateful)

kbin wasn't federated yet when we jumped. as far as i'm aware i made my kbin account like 6 hours after federation, because i did that as soon as i heard that there was a different UI

Lemmy has been around for much longer than kbin. So it obviously has more number of users in total. A better figure to compare is the monthly active users. According to FediDB, kbin actually has more monthly active users than Lemmy.

Lemmy was just ready first. Kbin at the time wasn't linked to the other instances yet, and was very slow, and had a lot of cloudflare issues.

It really doesn't matter long-term because Kbin can interact with Lemmy anyway.
