SharePoint succeeded because of balance of simplicity and flexibility to the next level. One advantage of this decentralized and empowering approach is that staff can quickly correct errors or make essential changes without encountering bottleneck. Users enjoy the ease of using SharePoint in many countries and with many languages, and the flexibility of interacting with the CMS differently depending on their skill level. Non-technical staff can also expand their assigned section by adding pages or sub-sites with minimal training and web team involvement. This allows content to be not only developed creatively, but implemented on the web in-country or within the department.
One of the most important capabilities of SharePoint 2010 is the Managed Metadata Service which provides support for modeling and deploying a rich corporate taxonomy.
