Loren Baker at Search Engine Journal has an extensive look at how Google might leverage their acquisition of Neven Vision to help identify and inter-connect users’ various web products (blogs, forums, social networking sites, etc) that might not otherwise be shared under a common login. The conclusion:
…if social networking is the future of online communication and Google is going to use Social Network profile information to personalize their search engines, but does not have a way of identifying the owner of the profile on some social networks due to no advertising in the network or no Google partnerships, what is one object or identifer that most users or members of Social Networks, Blogs, and Forums post that Google can use Neven Vision to help define that user?
