This is the software publisher's description.

Platform that invented professional-grade blogging, powering the biggest and most successful blogs for pro bloggers, publishers, organizations, enterprises and businesses of any size. As blogging continues to evolve, Movable Type leads the way with reliable service, outstanding performance and continuous innovation.

With more than 50 new features, MT4 will enable you to quickly start a blog, easily manage entire blogging websites and better connect with your audience. Here are some of the ways we are making Movable Type better than ever:

You’ll be up and running in minutes with MT4’s easy set up. Once it’s installed, you’ll be prompted to select from dozens of new professionally designed default templates and themes, or to import blog content directly from another blog platform.

MT4’s core authoring functions allows you to manage assets with greater ease. A rich web editor offers “What You See Is What You Get” functionality to allow insertion of not just text, but audio, photos, and files as well. And you can easily reuse any of those rich media assets with MT4’s new built-in asset management system.

Movable Type 4 offers a powerful summary of your blogging activity via a convenient single screen. Dynamic graphic displays let you see what’s happening with your blogs, which content and which contributors are driving conversations, and provides smart starting points for you to manage your site.

MT4’s powerful templating system lets you output content in any format, without requiring any programming or scripting. You can create standalone pages that automatically inherit the design and layout of your blog, and publish any content with the new posting interface, including rich media.
