Google I/O 2008 – OpenSocial, OpenID, and OAuth: Oh, My!
OpenSocial, OpenID, and OAuth: Oh, My! Joseph Smarr (Plaxo) A number of emerging technologies will soon collectively enable an open social web in which users control their information and it can flow between multiple sites and services. OpenID, OAuth, microformats, OpenSocial, the Social Graph API, friends-list portability, and more will be discussed, as well as a coherent vision for how the pieces fit together and how developers can start taking advantage of them now.

I was looking for a good overview of opensocial and all I could find was code tutorial videos.
This video is exactly what I was after.
Thank you for finally delivering a clear understanding of all these new services. I pretty much knew what they did, but I had to learn everything on my own from here and there, picking up pieces and trying to understand how they will come together. Good job.
Im impressed .!
This video in particular is amazing! It was very informative about the current situation developers face, and the current situation that users face. Almost deja vu to hear this speech. It was very easy to relate to everything you said. ;p
Joseph, you did very well!
this video worth every second and every word!
I became very interested in the socialweb and all these O’s.
FIVE STARS for sure!
well done! really!
