It's a great way to stay on top of all the new music that's been posted since you last visited. If there's not much going on then hit the Discover link to find active profiles and Groups you like. Following them builds up your network, so anything that's posted is available to listen to in your Stream.
The more you build up your network, the better your Stream gets. Invite your friends, follow people, subscribe to your favourite music websites (Sources) and start some Groups, then never visit another website again to discover great music!
