I don’t think it is the greatest CMS, it’s seems you need to do a lot of work arounds and add plug-ins for it to run properly and be flexible as most other CMS’ (Silverstripe, CMSMadesimple, Drupal etc.). With that said, it looks to be an great blog management system. I’d say use the CMS’ I’ve mentioned above for most flexibility and if you want a easy to use blog one day then think about WordPress.
