Both kbin and lemmy utilize parts of the activitypub protocol - a generic way for different social media sites to talk to one another - to make a reddit-like functionality. This means that regardless of whether you are on a server which uses lemmy or kbin, they can access and use each other. The only real difference for users is going to be the UI and that kbin has also used activitypub to give its users some dedicated mircoblogging capabilities (think mastodon). My advice is: if you are only interested in a reddit-like experience then use the one with the UI and community you perfer, but if you want an all-in-one account (and are okay with the added complexity that comes with) kbin is closer to what you want.
Karma is the total upvotes - downvotes across all posts made by an account on reddit; on the fediverse there is only upvotes (likes or boosts depending on implementation) and downvotes (dislikes) per post. Theoretically you could calculate it for your account, but because you cant display it anywhere (and it isnt used for anything) it wouldnt be of much use.
Out of the handful of good things CNN did, demonstrating the failure of libertarianism and getting r/jailbait banned is near the top.
Yeah, in the lemmy source code they are called "Communities"; in the kbin source code they are called "Magazines"; I think Mastodon uses the ActivityPub lexicon and also uses "Groups" in it's source code. I perfer "Communities" because that is how the "Groups" are being used.
Currently using Nobara OS and Vanilla OS. I really like Nobara because Fedora is a well supported OS (Thanks RHEL) and Nobara made setting up fedora really easy on my AMD CPU/ Nvida GPU. The only other ones which I liked as far as the out-of-the-box experience was: Endeavor OS for Arch-based and Zorin OS for Ubuntu-based. I appreciate Vanilla OS, and while they are pitching it as something for beginners; it is absolutely not. You need to understand at a basic level the relationship between containers and the host system, apx is a beautiful piece of software which makes containers incredibly easy to use, but you still need have a basic understanding. You also need to know when to interface with the host system, e.g installing gnome-tweaks. You also need to know when the default Ubuntu container isn't the best container to use. That said, the transaction system for manipulating the two root directories and most software being siloed off in containers ensures that the shitty laptop I am using hasn't ran into the many issues I have had in the past with it breaking updates randomly.
I would also suggest starting communities! The bystander effect is strong, dont worry about things too much right now as everything is still relatively small.
To get these in front of the devs, you could open an issue in the lemmy-ui repo: https://github.com/LemmyNet/lemmy-ui/issues
Oh, yeah I guess that would be an instance admin thing cause mine has a whole bunch in that settings box. Let them know that "undetermined" needs to be included as an selectable language.
On the web interface, go to your account settings and out of all the languages selected; ensure that "undefined" is one of them. You can select multiple languages by holding down the "control" key and clicking. For example, right now I have both "english" and "undefined" as the languages I use.
Searching for it in the search bar from within your instance is usually enough (the very first time it may not work show up as everything gets synced). If you want to ensure it shows up on every instance than yes you will need to make an account on every single instance and follow. Generally though, as more people start subscribing and searching; this will naturally happen.
This is one of the reasons why mastodon doesnt have re-boosts, only boosts and replies.
