Could we please be a bit nicer to new users?
Why is insulting other users and giving sarcastic comments such a huge part of the culture on SO? It's the complete opposite of projects like Wikipedia where everybody is exceedingly friendly and helpful.
For example: This response comes from a user with 13k reputation to a question about an interview problem:
There are a fair number of undergraduate CS students who can see this solution immediately, and it seems they were looking for those students. If you have any ambition as a C++ programmer, and aren't already intimately familiar with the data structures and algorithms provided by the STL, you should learn them now. It seems your competition already has.
This was in response to a genuinely extremely difficult interview problem that did not even ask for a solution using the STL. This seems to me like an unnecessarily unfriendly thing to say. This is just one example of what I think is a major trend.
