I felt I was a bit hard on you in comments before, so I went looking for evidence to support your claim.
What I found was that you are one of the people guilty of answering these questions.

Do malicious web sites ever exploit vulnerabilities in Linux clients?
This one is open as of now but is off topic as too broad by my vote

You write a big rant basically accusing every one of this
Collective “On Topic-ity”
I see users from anywhere in the 1-7000 range answering these questions
I hope this shows you that it is not so black and white with closing questions, you are just as guilty as the next user for overlooking them.
Based on this and the terrible example,that is on topic,you gave me, I don't see this as an issue with the site, more with your perception of the questions at hand, I am sure that users are not just starting to answer off topic questions just because they want too.
