Google introduces yet another services building block - Google Profiles.

A Google Profile lets you have a coherent identity and a simple way to manage your contacts across all services.
The new Google Profiles are already available in Shared Stuff, Google Maps, Google Reader and will be added to other web applications. If Google now finds a way to have Google Profiles certified and tied to a real person, they could finally create a spam free email system. Something Microsoft has not pulled off yet. Google is big enough that they could carry a new email network only consisting of verified members. It really would be time for a Spam free email communication, don't you think so?
