Facebook adds a timeline to your profile.
Mark Zuckerberg yesterday unveiled a new and one of the most powerful feature to date @ facebook. This one adds a real time ticker of your activities on your profile for your friends to see. They can now see what music you are listening to, what news you are reading or even what pics or statuses do you like. This in turn creates patterns with respect to you and their other friends, which allows them to see things like which artist do friends like in common and along with other things of interest. Personally i see this leading facebook to the waters of twitter(the timely status update of all your friends) dominance and it would be interesting to see how twitter replies to this competition.
