It seems to me like the author is jumping to conclusions. Just because no one cares to answer his question, does not mean the Quora is a "dead man walking". Quora has value not because of the amount of content, but because of the community. If I wanted nothing but lots and lots of content, I'd look to Yahoo Answers. However, I'd rather go to a website where very smart, experienced people are often willing to answer questions in detail. If someone pointed me to a source with the answer to my question, I wouldn't be offended, I'd be glad. The author seems to have taken a little offense that few people if any were willing to spend the time to write out a reply to his question.
