The amount of resources they have that at the very least provide a starting point to customize content, tools or resources for your business purposes. Looking at what they provide is a great way to get started with any project.

There's always a template to help me out when I need it. Also the project management tool is pretty good.

I like the live team project/task management. Being able to set up certain calendars based on the tagging system has really been helping our team.
