You all probably remember last week when Facebook introduced “like” button letting people to recommend web sites to friends. This feature is more social version of Web link, but search engines may not have access to data about recommendations.

They say Facebook’s “like” may spell trouble for Google. Read CNN collumn about this issue HERE.
