Google’s OpenSocial is definitely a shot across the bow of Facebook. Google’s idea is to create a common API that can be accessed by any social network to exchange data with them. Out of the gate, Google’s already gotten support from Engage.com, Friendster, hi5, Hyves, imeem, LinkedIn, MySpace, Ning, Oracle, orkut, Plaxo, Salesforce.com, Six Apart (Vox, LiveJournal, TypePad), Tianji, Viadeo, and XING. This is big news that will no doubt impact the social web for the next several years.
What’s the next step for Google? A: World domination.
