"The structure is basically HotorNot/FaceMash"

The biggest advantage of Drupal is, that probably you won't have to write a single line of code for this. You would need to learn how Drupal works (on a high-level, basic stuff), then just piece together existing modules and configure your website. That's the main idea behind Drupal - to be able to build and maintain websites without the help of a developer. This doesn't mean that the resulting Drupal module code is overly complicated and difficult to maintain, quite the opposite, it has a great community with high coding standards. Drupal was also meant to be used to build community websites, so it supports structures for multiple users creating content.
