Hey folks! Just realized something that makes Lemmy different from Reddit. Because of the federation, your votes are not technically anonymous on Lemmy. At least, I think.
Although there’s no UI to look at a user’s voting history yet, one could conceivably be built by an instance. Perhaps coincidentally, I hear there’s instances out there populated by mostly bots?
You got some fairly techy responses to this question but just from an actually-using-things pov:
Yes they’re different softwares, yes they can talk to each other (mostly) fine. On Kbin your topic-focused discussion groups are “magazines” and over here on Lemmy we call them “communities”. I can sub to Kbin magazines from here on Lemmy, and you can sub to Lemmy communities too! So it’s functionally a shared pool of content and discussion, even though technically it’s two different platforms :)
There’s a really useful tool for browsing Lemmy communities by keyword here: lemmyverse.net/communities that you may or may not find easier than searching through the Kbin magazine list.
