This is one of the nicer additions to the Zune Social with Spring (Zune 2.5)...

friendsprofile

We’ve created a new page designed to give a comprehensive overview
of the music your entire circle of friends is playing. This “My Social” page
acts as your new home page, displaying an animated mosaic of artists
and album pictures automatically refreshed by the selections your friends
are playing. This dynamic view includes great artist images along with the
ability to sample tracks on your friend’s cards. Just mouse over images to
see who’s been listening to what.

As you can see in the profile of MOSSYROC above, you get to see how many plays he has, he most recent plays with download links too! A better friends list and more. Really nice stuff here and that is just the social view in the store.

Your homepage will have some neat additions too, like the what's happening, facebook style list.
