8 types of sites you can build with Drupal

In terms of social networking capabilities, Drupal is probably the best CMS. Out of the box, Drupal provides a pretty robust user management and permissions system, but if you want to create a real social network, you’ll need to use some modules. I will not list all the social networking modules for Drupal here because you can already find a page that does that in the Drupal documentation.

If you are looking for examples of social networks created with Drupal, take a look at Imbee or GoingOn.
