Social Petworking

For our weekly "knowledge share" in my digital communications class, my dear classmate and fellow blogger Helena told the class about two new social networks, Dogster and Catster. I'm still processing my feelings about this-- a mixture of amazement, joy, fright, and confusion. Might this be a sign that social networks have gone a little too far? Or maybe it's about time that we involve our faithful pets in the joys of social networking (a.k.a. petworking).
