Actually I've used OpenSocial once, and while it seems a reasonable idea at first, my open social experiment turned out to be a failure
Personally I think the 2 reasons of this failure were:
The O.S. standard (as you anticipate in your question) is not used by the most important Social Network.. so, unless you don't have to build your own social network, I think it is pointless to respect standard while you can define a communication protocol which meets your needs.
The current libraries that implements O.Social are not completed and sometimes are missing some important features.
We used http://code.google.com/p/opensocial-java-client/ thinking that a lot of things were already implemented (for not falling in NIH). We were wrong! Since there is none who ever developed some library that convert Facebook JSON or twitter JSON in open social standard (at least 4 mounths ago we were unable to find it), and I've developed those by myself. In the end we decided to left this standard and we moved to a solution more adapt to our needs.

实际上我曾经使用过 OpenSocial，虽然一开始看起来是一个合理的想法，但我的开放社交实验结果是失败的。
我个人认为这次失败的 2 个原因是：
操作系统标准（正如您在你的问题）没有被最重要的社交网络使用..所以，除非你不必建立自己的社交网络，否则我认为尊重标准是没有意义的，而你可以定义满足你的需求的通信协议。< /p>
当前实现 O.Social 的库尚未完成，有时缺少一些重要功能。
我们使用了 http://code.google.com/p/opensocial-java-client/ 认为很多事情已经实施（为了不落入 NIH）。我们错了！由于没有人开发过在开放社交标准中转换 Facebook JSON 或 twitter JSON 的库（至少 4 个月前我们无法找到它），所以我自己开发了这些库。最终我们决定放弃这个标准，转而采用更适合我们需求的解决方案。
