I have only an up and a down arrow, wtf is a heart react

FB meme

PieFed also offers emoji reactions, I see 3 distinct types on this post so far.

Do they federate with any other platforms?

…kinda?

They do federate, so that I can see reactions from other PieFed instances just fine. But Lemmy does not use the data for anything. It just passes it on for whoever can use it.

I was asking specifically about other “platforms” besides piefed because I’m curious how supported are emoji reactions across the fediverse. I had around a year of break form the fediverse so I’m a bit ootl on recent developments.
