The first hub, called “Newsfeed,” is focused on people and activity. The main page of this hub features the SharePoint newsfeed, and allows you to add your own personal SharePoint apps, like Tasks.
The second hub is “SkyDrive Pro,” a place to store your files in the cloud.
The final hub is “Sites,” which will help you keep track of the SharePoint locations most valuable to getting things done.
To power these hubs, we’ve introduced a concept called following. In SharePoint 2013, you can follow people, documents, sites and tags. When something is important or interesting, follow it. We’ll show you information about the things you’ve followed in your newsfeed. Also, we’ll keep track of those things and give you easy access to them from the three hubs.
In Office 365, Newsfeed, SkyDrive and Sites are joined by links to other products in the service, like the Outlook, Calendar, and People hubs from the Outlook Web App.
In the rest of this post, we’ll take a look at the contents of the Newsfeed, SkyDrive Pro and Sites hubs.
