I think we should regard this site as a collaborately edited Q&A book. Why book? Because it fits the "this is not a discussion forum" idea IMO. Consider a book that many people participated in its compilation. A person who collaborated with a question and another person who collaborated with an answer to that question aren't really communicating with each other face to face. Instead, it is one's question and other's answer is communicating. So, it would look bad to have greetings and thanks on such a material. Just like it, they look bad on Q&A format of the site.

Sorry for the late reply. I wanted to add this, because I think we aren't facing the issue head on. And I think If we don't stop this now, it will be harder to fix later. I suggest we be firm about this.
