@trwnh yeah i noticed on your reply to your own post that i wasn't really answering your question. having a hard time wrapping my head around what would be a suitable answer tho.
i'd say it can also be a way of being talked to, not just about. just, the intended audience is a different one. similar to replying and then boosting your own reply, it talks to your own audience as well and not just the author of the op.
