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
Liftoff still is my preferred option over sync. My only problem with liftoff is I don't like the way it shows replies within longer comment chains. It's too cluttered. Sync does a better job there
