If you are using LinkedIn (which I hope you are), you should be following your Network Updates via RSS. How many of us constantly check our Linked In page? I’m sure even the best of us do not. But if you put those updates in your favorite RSS reader, you will always be aware of who just connected with whom. You will know who just joined a group that would probably be good for you to join. You will know when someone just dropped some important news. All of this info coming to you with little effort. Using RSS for LinkedIn this way gives you another stream of updates similar to Twitter, but more focused on business. And just like Twitter, when something of interest hits you, you can log in and participate.
