I'm curious as to why questions get closed at all. I understand that certain sects of SO adhere very strictly to the (frankly, esoteric) FAQ, but I'm at a loss as to why this functionality exists at all.
The reasons for my confusion are quite obvious:
- 'Closed' questions are still findable via Google.
- 'Closed' questions still allow commenting.
- The only thing that's really prevented is providing ongoing information with regard to the original question.
So why bother closing a question at all?
To be very clear. I'm not asking why questions get closed (although that's certainly a black box for pretty much all the users on the site as well), I'm asking what the point of having this functionality is at all since it seems to be essentially useless.
Please keep in mind I'm not commenting in any way on the criteria used to close a question, I'm simply confused as to why the function exists at all.
For example, I recently posted this question: Does SSL alone prevent SQL injection?
It was a valid question I had, since I was confused about the relationship between SSL and SQL injection attacks. I got an excellent answer from Jeff Olson, helped out at least one other person that had the same question, and now it's closed because it's "not constructive".
Here's the rub ... you can still find the question via Google, you can still comment on the question and the answers, but it's now closed so if anything changes in the future with the relationship between SSL and SQL injections it's now impossible to keep the information relevant.
How is this a good thing?
