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
I don't want to be a dick. All I'm saying is running such a poll is tricky as time of day as well as day of the week will impact the results drastically. Add to that the type of audience and then you've got massive skew.
