The application of Web 2.0 technologies internally within the enterprise. It refers mostly to the self-service phenomena of Web 2.0, such as blogs and wikis. One touted advantage is that when employees leave the company, their blogs can be searched by remaining staff to help them uncover information that would otherwise be difficult to obtain. Enterprise 2.0 also deals with other Internet and IP-based applications such as an enterprise-wide voice over IP (VoIP) deployment. See Web 2.0 and VoIP.
