Facebook has made its first steps into the search market. The social network has launched a trial of a feature called Questions, which allows people to pose queries to the site’s 500 million users.
The service has been rolled out to a select group of Facebook members and will “evolve over time”, the site said. It will go head-to-head with other services such as Yahoo Answers, Twitter and search engines such as ask.com.
