StatusNet是个相当老牌的开源微博程序，相当多的国外微博网站都是基于它架设的。不过StatusNet对于服务器的要求的确是多。
StatusNet的功能还是比较丰富的，除了微博必备的所有功能外，StatusNet支持自选背景和自选缩链服务，并且支持用户使用OpenID或者Facebook账户直接登录。同时支持通过Jabber/GTalk发布帖子和接受更新。并且支持大量的国外电信运营商（60多个），您还可以通过短信发布帖子和接受更新。
StatusNet集成Twiiter，可是实现Twitter和StatusNet的双向同步。发帖是也可以附加文件，如果附加的是媒体文件，则可以在线浏览。与Sharetronix一样，StatusNet平台中的用户也可以设置一些描述自己兴趣爱好的关键词，方便志同道合。

This release has been running on the StatusNet cloud (including identi.ca) for a few weeks, and we think it's stable and functional. Frankly, we should have probably got this out sooner, but we've been working so hard on the new StatusNet 1.0 release, we didn't have a lot of focus for it.
