Yes, SF is doomed just because it got it completly wrong and maybe even because its users are less incldined to provide help (answert) to others.
While you can all see that I do have quite a good experience on SO site, I could say the opposite abouyt SF. Why? Just because most people with moderation permission around here are some kind of ***holes that are inclined to find reasons for considering new questions off-topic instead of using their brains and trying to provide help/userfull feedback.
True, it is much easier to Flag than to provide a solution...
Proove me that I'm wrong, I hope so, still my impression is that most veterans here are bulling lower score users, something that you will not find on stackoverflow.
