Over a quarter of Lemmy users use Sync (based on a poll)
(loot.buckodr.ink)
I did a poll and nearly 30% of the people who voted said they used Sync! It's stayed around that percent the whole time too!
EDIT: Here is the poll I forgot to put this here like five times lol https://strawpoll.com/wby5A21R1yA
Heck, lemmy is barely supported. The dev just bootstrapped the lemmy API into the reddit app and published it as a beta. We were all happy for that, but it will be a while before it's a polished lemmy app.
