TheDude recently upgraded the server to the most recent version of Lemmy. You'll notice significant improvements to the user interface, and hopefully the functionality is also improved. There is no official changelog yet because this version is not yet finalized, but I'll link the GitHub releases page where it should eventually appear.

Edit: 0.18.1 is now fully released and we have upgraded to the final version. You can view the link above for the changelog.
Isn't Kbin 20% the size of Lemmy?
In reality, probably yes. But AFAIK there is no way to accurately track their active users. You can compare total users, but then you can't accurately measure Lemmy, because most accounts here are bots or abandoned.

Assuming their activity rate is similar to most Lemmy instances, you could estimate that about 25% of their 60k userbase is active, good for 15k MAUs, or just over 20% of Lemmy's 66k MAUs.
A long winded way of saying you are absolutely correct ๐
