Can Google challenge the very well established Facebook?
Google is all set to challenge Facebook with their upcoming integration for GMail called Google Buzz. Users can link their Twitter, Flickr, Picasa, and Google Reader accounts to their Buzz streams to see information produced by friends on those networks, as well as updates posted directly to the Buzz stream.
Buzz users will be able to see all the content produced by those who they are following, but they’ll also be able to see content produced by people they aren’t following if their friends “liked” or commented on that content.
They’ll also be able to train that algorithm by clicking “Not interested” on these “recommended” status updates if they don’t wish to see that particular type of update again.
