More Social Networking

In addition to my accounts on Facebook and MySpace, I now have a linked in account. The address for this is: http://www.linkedin.com/pub/7/997/a70. I am interested in explore this more. Also am going to explore ping since I keep hearing that name, but don't know yet if I will set up an account for that. I feel a little quilty taking up all this space on these sites! Feelin piggy.
