TechCrunch上面的消息：Yammer获得techcrunch50评选第一名，Yammer是一个企业级的Twitter模式应用，适用于企业内部的信息交流和在线协作，可以用来讨论创意，分享信息。twitter是“What are you doing?”，Yammer则是“What are you working?”

以下是TC50上面对于Yammer的介绍：

Yammer is a tool for making companies and organizations more productive through the exchange of short frequent answers to one simple question: “What are you working on?” As employees answer that question, a feed is created in one central location enabling co-workers to discuss ideas, post news, ask questions, and share links and other information. Yammer also serves as a company directory in which every employee has a profile and as a knowledge base where past conversations can be easily accessed and referenced. Anyone in a company can start their Yammer network and begin inviting colleagues. The privacy of each network is ensured by limiting access to those with a valid company email address. The basic Yammer service is free. Companies can pay to claim and administer their network
