Enterprise Web 2.0 is changing the way that knowledge workers interact with information and one another. The implications are huge and could lead to a fundamental redefinition of collaboration and business process. The biggest IT vendors have a lot to gain and a lot to lose in what could be a major shift in the productivity landscape. Each brings strengths to the table, and each faces challenges. The battle for mindshare with enterprise users is on, and the stakes are high. In the midst of this, information and knowledge management (I&KM) professionals must create an enterprise Web 2.0 strategy. Properly identifying the right vendor for your organization is all about aligning each vendor's value proposition with your identified needs.
