-You can also use your Identity Address or other people's Identity Addresses to become friends across networks. The list of possible networks is growing all the time. If you know (for instance) "bob" on identi.ca (a Status.Net site) you could put bob@identi.ca into your Contact page and become friends across networks.

Google Buzz does not yet support all the protocols we need for direct messaging, but you should be able to follow status updates from within Friendika.
