I don't feel as strongly about quote posts as I did in 2018. Personally, I am not a fan, but there is clearly a lot of demand for it. We're considering it.
If we did do it we'd like to make it something you can opt out of, in a similar way to how we plan to allow disabling replies. It's not entirely trivial.
@Gargron disabled replies is one of the more frustrating features of Twitter.
On Mastodon, you can already only ask the people who are following you. Disabling replies leads to public posts with questions you can’t answer.
