Just like Google and MSN, Yahoo is always keen to expand the different kinds of services provided. In a recent move, Yahoo has started a service Wednesday that allows users to get their questions answered online. The service is free, and is provided by volunteers. Dubbed "Yahoo Answers", the service allows users to submit questions on any topic at answers.yahoo.com and wait for others to post responses. It's possible to rate responses on quality, in order that inaccuracies are cut down to a minimum.

Ofer Shaked, director of engineering for Yahoo in Sunnyvale, said that the goal is for users to share knowledge, much like they already share photos and opinions within the Web site's Flickr photo-sharing service and Groups areas. Some users may even gain a reputation as experts on certain topics based on their highly rated answers.
