Keeping up with the 2010 Winter Olympics in Vancouver will be easier with Yahoo's Mobile site, m.yahoo.com/olympics. Although it doesn't have video, Yahoo's mobile site has still photos, live results and a complete schedule of all the events. The site also has blogs, commentary from experts, and a robust search function which will allow users to search by sport or athlete.
 
With big name sponsors like Visa and Samsung, kudos to Yahoo for their innovative approach to provide users what they need.

(Businesses; are you convinced yet that you NEED a robust website to compete in today's web & mobile savvy world?)
