The above was only an example of it's use. It's really a good blog and it uses templates. Users are able to choose themes and have there own home page. It is developed by the guy that is developing this cool site.
Well I'm not that certain actually. I've looked around and tried Drupal and Nucleus and my appraisal was that Drupal was more heavy-weight. Also, Nucleus does seem to have an easier plugin process.
