What's amazing about OpenSocial is how it accelerates the pace of interconnection, previously rampant mostly within single, rapidly growing social networking communities. OpenSocial ties these fast growing communities together for a quantum leap in value and connection (to people, groups, organizations, philanthropic causes, etc.) Blogging, tagging, media (video and picture) sharing, and online personal or professional communities have become interconnected. Browser technology, such as from Flock, add to the usefulness of these ever-more useful tools. They are also ever-more intrusive and everyone should recognize (and maybe restrict) the personal information sharing, which can be automatically enabled within some of these online services and applications.
