An interesting aspect to the system is the concept of Friend Management.  In our organization, this is sleeper functionality.  When you befriend someone, you can use labels to organize your friendships into meaningful groupings. In the UI, go to Your Stuff > Friends and on the right hand side you'll see the Add/edit Labels.

You might be asking: What can this do for me?

By grouping your friends/connections into these buckets, you get an RSS Aggregation feed that notifies you when anyone in that grouping performs an action.

This is a very powerful way to follow people in the organization, whether you are in the SBS Dashboard, RSS Feed Reader, or external system with RSS Consumption Services.

Users can have multiple labels, so you can bleed a person across the different areas as you deem necessary by simply applying multiple labels to your friends.  Another important element is that this association is controlled by the user, not by the system.

It's pretty easy and very powerful, so give it a whirl and let me know what you think!  Any one have any other sleeper features they'd like to share?  Shout 'em out! =)
