Possibly, assuming Facebook accepts this invitation, OpenSocial will unite most of the major players in social networking arena. From the moment Google introduced their OpenSocial platform, where developers can write applications for all participating networks (MySpace is one of them), Facebook was somehow reluctant to join.

Although Facebook is seen as a major competitor for MySpace, there is an opinion that in fact they can co-exist and they are not as similar as they might appear at the first glance.

Being able to develop applications for social networks without worrying about transportability and making them available across the board is a great thing and hopefully Facebook will join Engage.com, Friendster, hi5, Hyves, imeem, LinkedIn, MySpace, Ning, Oracle, orkut, Plaxo, Salesforce.com, Six Apart, Tianji, Viadeo, and XING on the OpenSocial platform.
