Nobody ever wrote a book on why and when should a thread be pinned. Nobody has taught no one how to think. Therefore, my scholarly background cannot help me help you here.
Basing my thinking on rational human thinking, the reason why a thread is pinned is that it is of great importance, and it is likely to draw more views and replies.
So in his wisdom, or lack of it, the ‘MOD of the year’ pinned this thread :
After 24hrs it has generated 44 replies and 500 views
pinned threads easily do 200 replies and 4000 views
This clearly shows how the thread is of no consequence to the honorable villagers
It is an ego rubbing endeavor that has fallen flat
I know it is, i have seen a similar scenario with cheki maneno
I therefore request eating of the humble pie, and unpinning of the thread if not pulling it down
Moral of the story: if you are not important, nothing you say is of importance
