This is how I perceive it. A conversation or discussion when someone starts a thread. I have never heard of or seen this line drawn between "advisers" and posters. It's a very odd view. It implies some sort of responsibility for whatever "advice" is given, when in fact people may make suggestions, ask questions share experiences, etc more like a conversation.
It's bizarre to position a relationship/general forum as if it's a psychologists office and there's someone on the couch and other's sitting with notepads and diplomas on the wall. It's like any other conversation anyone would have with a friend, the bartender, whatever. The ena shaming, when certain posters don't hear what they want to hear comes across as people who want to cyberbully and unload a lot of negativity, not come for a discussion about an issue.
