The fuss is that it's not WordPress or Joomla :D
To answer the original post: This is a CMS for developers and users.
Having developed sites with both Wordpress and October I came to the conclusion that Wordpress is more suitable for non technical people who want a simple business site or blog. Most hosting companies have one click wordpress installs and the user can just add plugins to create the functionality they need without ever touching a line of code.
October CMS on the other hand, offers a solid base to get a simple website up quickly and then develop that into a rich web interface or application. Yes, you have to know some HTML but building a website is a technical task and dumbing it down with drag and drop builders results in poor quality websites that are slow.
Once I show October CMS to clients that have no technical knowledge, they immediately comment on the design and ease of use. With a few client friendly plugins like Pages, Blog and OctoDoc they get on just fine and can manage the site content by themselves.
