years ago i was a member of a large community on slack that had a custom emoji 🇮🇪 that rendered as the Internet Explorer icon, and it was adopted within the community to indicate "i am very out of date / belated wrt a previous discussion, but having just read it, i want to add something new". this is the kind of thing i do a lot, so i used it a lot there, and now i find my brain still reaching for it, a semantic void, a phantom signifier
