Because of this the policy now is that some duplication is good[1]. Though a lot of users are still rabid about closing, I always try to answer inexact duplicates, and if the their title doesn't lead to duplicates, point out the things they should have searched for (ie, object picking, hit testing and point in path are three names for very similar things)

Eh. I'm to the point where I see an attempt to "fix things" on their end ... I just hear "we're sorry its broke, heres a fix that should have been there a long time ago."

Or when I click through to the question it "duplicated" only to find that that question was never really answered either.

My question about extracting valid emails got closed as a duplicate of a question about validating emails.

The answer they provided? "Try to send an email there and if it works, it is valid."

How is this supposed to help extract emails from text? Stack Overflow has become a hostile and unhelpful place.

I like that most of those are closed quickly. But, I'm not sure how you'd solve this issue. The current feature they have tries to find a related question based on their title, but not the content.
