Yesterday’s joint announcement by Facebook and MySpace was, as expected, about the latter building the former’s social graph into its service. Mashup with Facebook is a new feature that lets MySpace users import their Facebook likes and interests, using them as the basis for a personalised entertainment stream. “This new feature is a great illustration of our strategy around social entertainment and enabling the real-time stream,” said MySpace CEO Mike Jones. MySpace will also be recommending new topic pages and profiles based on its users’ Facebook data, and also plastering its own site with Facebook Like buttons for content. There are two ways to look at this. First – the angle taken by many tech blogs – is that it’s a ‘surrender’ by MySpace in the social networking wars. However, the second view is that this could be quite powerful, marrying the Facebook social graph to MySpace’s huge database of music artists.
