The popular corporate social networking site LinkedIn has recently launched a new service called “Answers”. It’s not much different than what Yahoo! offers, but instead of covering a wide range of topics, LinkedIn: Answers covers a smaller range of niche topics from Business Administration to Hiring and Human Resources.
Also, you can limit who can answer your questions, from the entire LinkedIn network to just people you are connected to. Since LinkedIn is in direct competition with other networking sites, this could become a very hot feature for them.
