Continuing this discussion of "web 2.0"....

Moving beyond the basic dynamic website model, we get up into the realm of the content management system, or "CMS" -- a dynamic site where not one but several people -- thousands, even -- have direct access and ability to update and add to the website's content. This is what we create with websites powered by Drupal.

What's appealing about CMSs like Drupal is that they can be used for just about any website, from small business to large corporation to online community to non-profit organization. Just about any organization with any sort of web presence can benefit from having a website where many people can participate at different levels of access.

The power this affords, for example, to an organization like BlogHer is profound. Their website last year was basically just a blog. Now it is an online community with literally dozens of blogs, oodles of members and many powerful tools at their disposal to not only disseminate information but also engage people in discussions on topics spanning the globe.
