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
^ It's honestly amazing! (not to say others aren't, just my personal favorite of the ones I've tried)
