This was just closed and I don't understand why. It says off-topic, but it is specifically about programmers and not a poll nor does it meet any of the "do not ask about"s in the FAQ, in fact in the do-ask-about's of the FAQ I would place this under "business concerns" from the description of the article.
Call me crazy, but I'm rather certain if I posted a question asking:
"Can anyone direct me to this blog I read that detailed online security, it was about how passwords are shared around every site and had a comic about a gordian knot and some xkcd about a battery and a horse"
I would get the answer with link pretty quickly, and it would serve as a reference for future programmers who couldn't remember where they saw that blog. It's specific so not a poll as book requests are, it's constructive because it will direct people in the future to a valuable article on an important topic to programmers.
So what's wrong with the linked question?
