有谁知道那个jive到底是个什么东西么？今天上微博看到都要上市了，打着“企业社交软件”的概念，但是没明白是企业和企业之间社交还是企业内部社交？

哈哈，他们有两套产品。一个是内部的，一个用于与客户和更广泛的社区交流
"Jive provides two products with the Clearspace name, both of which run on the same platform. The one getting upgraded is simply known as “Clearspace” and is used by businesses for internal collaboration purposes. This means holding discussions, sharing and working on documents, blogging, running polls, organizing projects, handling group tasks, and more. The other product is called “Clearspace Community” and consists of software that businesses can use to communicate with customers and the broader community."

jive的前身其实就是一个类似discuz一样的forum，不过是用java开发的。因为设计的不错，后来分裂成了2个分支，一个开源免费（名字不记得），一个就是现在的商业软件公司jivesoftware，现在已经有了自己的一系列社区软件。早年学习java的人应该知道jive forum这个软件，很早很早以前学习设计模式的时候，一般都拿它的源代码作为参考，它是早期对设计模式运用的一个典范

jsp的典范嘛。
