@Mastodon Not sure whether I'm a fan of the pop-up style notice. Both features have an interesting use-case but I think I'd prefer to have them inline.

E.g. having a pop-up for each individual, reminding you of etiquette quickly starts to be 'just another annoying popup' and I guess people will quickly disable the reminder altogether.

While an inline profile summary of the person you're replying to for the first time would be less intrusive to your interaction and still provide helpful info.
