It wasn't even a "discussion" (specifically forbidden because independent thoughts and points or view are something frowned upon on SO, which is bent on crushing individuality)... Just a friggin' good list.
The really pathetic behavior of SO mods starts when they see people criticizing SO (and leaving or rage-quitting SO) and then try to say: "Do not speak about it here (e.g. on HN), bring this to meta".
Yeah. Sure. Meta is even worse than SO ; )
As a result of this crazy mod behavior people, like me, are quitting and stop helping others on that medium.
It's not that big of an issue that said because something, one day, will rise just as fast as SO did and shall have fixed the arbitrariness of SO mods behavior / rules.
A pet-peeve of mine is that they clearly said on SO (on Meta) that it was OK to rewrite a question entirely so that the question fits a totally bogus response (totally bogus response of course made by a user with lots of rep).
When I saw that non-sense I realized it was time for me to quit.
