The wildly popular niche social networking professional networking site, LinkedIn, just launched their Answers service, mimicking another very popular service, Yahoo Answers. For those not familiar with Yahoo Answers, it's a Question and Answer format forums-like community where anyone can ask questions and based on the activity on the site, hopefully someone answers your question. This is definitely used to add stickiness to the site and hopefully add a more engaging element to the site. This equals more page views and further seperates itself from the other smaller niche, professional social networking sites. Source: http://www.606tech.com/fullarticle.php?artid=281 JFYI: Ruslan
