OStatusSNS狀態(tài)更新協(xié)議

OStatus 協(xié)議可以讓不同社會(huì)網(wǎng)絡(luò)平臺(tái)的人互相可以關(guān)注對(duì)方，而且對(duì)使用者來(lái)說(shuō)是完全透明的，你可以通過(guò) OStatus 獲取好友的更新信息。目前支持 OStatus 的有 Google Buzz, StatusNet, WordPress.com。

還有一些跟 OStatus 類(lèi)似的協(xié)議如下：

• Activity Streams encode social events in standard Atom or RSS feeds.
• PubSubHubbub pushes those feeds in realtime to subscribers across the Web.
• Salmon notifies people of responses to their status updates.
• Webfinger makes it easy to find people across social sites.
