We continue to invest in the best of innovations. Consumer trends change over a period of time... We made sure our products have deeper relationship with Facebook and Twitter, we're in partnerships with them. There's a huge amount of traffic coming in from social networks, which is incredibly important. We think social is not necessarily a destination, it's a behaviour. What we think about offline, we try to replicate it online. There are verticals, but behaviour is pervasive. As long as we help people create a social graph of their own and tap into it and share their content, that's an enriching experience.
