This year enterprise 2.0 went from being a fringe idea to being mainstream as CIOs started asking "how?" instead of "why?" Big name vendors entered the marketplace with new products and existing vendors released new versions with innovative new features.
We chose to break up the enterprise products of the year up into categories: new product, e-mail, mobile, development tool, database, social software suite, social CRM, microblogging, conferencing and CMS. Products were evaluated based on market performance, innovation, utility, impact on the space as a whole and improvement over last year. Each of these products either changed the game, or won it.
