Google kind of innovation needed?

Social Networking websites have flocked in large numbers with none of them been google type innovation. Do we need innovation in social networking space? Yes, there is a site http://www.orkut.com and there are various others. But, do they really provide enough compelling tools and services to empower social networking? I do not think so.

I firmly believe that it is just search which has seen Google.com. Other spaces still need google kind of innovation. So, creative minds out there, keep brain-storming.:)
