Firstly: The below will quickly turn meta - so you might consider skipping?
Or just mentally label everything from here with "OT" - and appreciate that you were warned.
So, we found the below on Wikipedia, the free (=please donate) encyclopedia - on the topic of Off topic:
In the context of mailing lists, discussion groups, discussion forums, bulletin boards, newsgroups, and wikis a contribution is off-topic if it is not within the bounds of the current discussion, and on-topic if it is.
Even on very specialized forum and lists off topic posting is not necessarily frowned upon, but a common netiquette convention is to mark a new off-topic posting or email with "OT".
Posting off-topic messages to deliberately aggravate other members is a form of trolling.
We do not intend to earn ourselves a trolling title.
Therefore, this entire section was labelled OFF TOPIC - thereby seemingly guarding us from direct critique?
Per definition it is not really possible to tell for sure what you will find.
You were warned.
