What's the difference between lemmy and kbin, as far as Sync is concerned? I don't mean APIs, but in terms of user experience, what would change for me coming over from kbin?
You should theoretically have access to the same communities/magazines.
On desktop kbin seems to have nicer looking UI and also seems to have better sorting algorithm (at least by default) because when I connect to lemmy server even though I subscribed to the same communities, it feels more deserted for some reason.
Hm, maybe it's called something else. I know that lemmy will default to post's language to "undetermined" if not manually set upon submission. This means if you disable it as a language option on your profile it won't show up. I'll try and get on kbin and see what the equivalent is. Because I have to go to the website in my browser to be able to reply to you. I'm sure apps will allow setting language on a per comment basis in the future but for now this is it.
