@taylorlorenz i disagree that they won't stick around necessarily... but it really is a useful feature, contrary to the beliefs of some here.
A few notes though:
1. Multiple mastodon forks have QT functionality. I expect that will expand.
2. QT was only added to Twitter in 2015 (and only named QT officially in 2020) so the site did exist before it with plenty of users...
3. I expect that we'll start to build some norms around here regarding the feature that make it even better than at Twitter.
