Is Linkedin Answers the answer?

LinkedIn Answers was launched this week. Today I posted the question:

"Will LinkedIn Answers reduce the need for user manuals and technical authors?
Or are these services needed as a result of the "missing manual" syndrome?"

See http://www.linkedin.com/answers?viewQuestion=&questionID=6759&askerID=39724

I received 13, very thoughtful, answers.

What do you think?
