Quote-post (Bluesky)
A Bluesky feature for quoting a post with your own comment — but with controls Twitter lacks: you can detach your post from a quote, and the author can turn off quoting entirely. An attempt to tame "quote-dunk" toxicity.
The problem it addresses: on Twitter the quote-tweet became a harassment tool (quote someone to mock them in front of your own audience, with no way for them to defend themselves). Bluesky first let everyone quote freely but added: (1) "detach quote" — the quoted person can remove their post from the quote so it goes empty, (2) a setting to disable quoting on a post. It builds on the AT protocol's data model where relationships are explicit records that can be revoked. Shows Bluesky's design philosophy: give the user granular control over how their content is reused. A contrast to Mastodon, which long avoided quoting entirely out of the same concern.
