FaceBook задал жару

обогнал новой идеей всех на пол года, но теперь товарищи ниже "дружат против" фейсбука. С таким набором скорее всего им не останется ничего другого, чем в конечном итоге поддержать ту же технологию

Many sites, one API
Common APIs mean you have less to learn to build for multiple websites. OpenSocial is currently being developed by Google in conjunction with members of the web community. The ultimate goal is for any social website to be able to implement the APIs and host 3rd party social applications. There are many websites implementing OpenSocial, including Engage.com, Friendster, hi5, Hyves, imeem, LinkedIn, MySpace, Ning, Oracle, orkut, Plaxo, Salesforce.com, Six Apart, Tianji, Viadeo, and XING.


In order for developers to get started immediately, Orkut has opened a limited sandbox that you can use to start building apps using the OpenSocial APIs.
