Though I'm not saying there aren't good points here, there are many, I think it's interesting to consider the usual impact of discussions on this subject - typically a great deal of insecurity/defensiveness (I feel it too), which I don't mean to say in a negative light, in fact I think it's quite natural. It's worth quoting Steve Yegge's fantastic 'get that job at google' [1]:- 'Me: blah blah blah, I like asking question X in interviews, blah blah blah... You: Question X? Oh man, I haven't heard about X since college! I've never needed it for my job! He asks that in interviews? But that means someone out there thinks it's important to know, and, and... I don't know it! If they detect my ignorance, not only will I be summarily fired for incompetence without so much as a thank-you, I will also be unemployable by people who ask question X! If people listen to Stevey, that will be everyone! I will become homeless and destitute! For not knowing something I've never needed before! This is horrible! I would attack X itself, except that I do not want to pick up a book and figure enough out about it to discredit it. Clearly I must yell a lot about how stupid Stevey is so that nobody will listen to him!'
