In the mastodon/Calckey world you can migrate your account on one instance to a new account on a new instance and all the people following you will transfer and automatically follow your new account. So you don't have to be all "Hey moving to [xyz new instance] follow me there!"
That's something that's in the works for kbin and Lemmy some day
When you submit a reply or a post, always save it to your clipboard first. Lemmy has swallowed my responses many many times. In fact, it took me about 5-6 attempts to submit this comment.
Oh hey, the star is there for me too. As an old, I sometimes have issues recognizing all the diverse pictograms that modern tech design uses. Many of them are not intuitive, or are not standardized enough to assume any meaning without prior experience. In this case they're also really tiny on a phone screen.
On that note, upvotes and downvotes upvote matter even less here ("here" meaning kbin) as the factor dictating comment order in the "hot" ranking is boosting (think retweet equivalent), not the vote count.
Kbin is also like Mastadon. It's basically the same thing as lemmy, just with a slightly different user interface. (I personally like it better, which is why I'm here, lol.)
The main kbin instance, kbin.social, is hosted by a guy called @Ernest, who's also the main (only?) dev who created kbin. But there are other kbin instances hosted by totally unaffiliated people, too.
