When Web2 became named, a lot of us were excited, not by the frivolous apps, names and pastel colours, but because the functionality is what organisations have needed for years. Email, like democracy, is not perfect but it was the only system we had. With wikis and human categorisations, meaning was made that added meta-value over and above the file name. Enterprise 2 hyped? Its not hyped enough. Oddly, its usually top-level management and the knowledge workers who get it.
