Easier reporting of aggregate data
I have a school wide side with 20 "projects". I find it very easy to export data on the projects, but it is extremely difficult to find easy data outputs for all projects as a whole for the school. When we go to the main site, I would like the site owners be able to look at data for all of their projects in one place.

If you have a group site, you can go to the group manage section and see graphs and reports across all of your sites.
