Dan noticed this article in which CNET says big business is embracing Web 2.0, which in this context seems to refer to the two-way web (or, as one author put it, the Living Web):
Though it lacks a precise definition, Web 2.0 generally refers to Web services that let people collaborate and share information online. In contrast to the first generation of Web offerings, Web 2.0 applications are more interactive, giving people an experience more akin to a native desktop application as opposed to a static Web page.
