Sony is looking to clear the air surrounding their upcoming PS3 online portal, Home. In a presentation given by SCEE's Darren Cairns and Liam Wickham at the Develop Conference event, they have outlined that the focus is on gaming and definitely not on social networking.
You may have come to the conclusion from the screen shots and features let out so far the vision for Home was akin to that of Second Life, but according to Cairns and Wickham it is the furthest thing from their minds. "Home is not a social network - it's focused on games. It's a visual representation of the PlayStation community."
