The web is better when it's social
is the first article on the blog;
Perhaps most interestingly, we will see social capabilities move into new contexts. OpenSocial will also work in non-traditional social contexts, such as on Salesforce.com and Oracle. With a common set of APIs, it will be even easier to extend social functionality. Beyond the many fun and entertaining social applications we already have seen, we think we'll see a number of social applications emerge in business contexts.
Lastly, the web is global, and so is the scope of OpenSocial. When you add up the current websites who have committed to implementing OpenSocial, you realize that a developer building for OpenSocial has the chance to reach over 200M+ users in dozens of countries. So over the course of the next few months, we're going to continue laying the foundations of OpenSocial to enable this common dream for a more social web.
So get started today. First, sign up for the Orkut sandbox so you can begin building and testing. Next, take a look at the OpenSocial API docs. Finally, start thinking about the possibilities given all of the websites that are implementing OpenSocial."
