If you already have a Friends group within your Google Contacts, youll be able to easily share with those friends on iGoogle as well.

If you dont care to share, iGoogles social features are optional and can be disabled on a gadgettogadget basis with just a few clicks. This appears to just be Googles latest move in becoming more like one big social network. It all starts at the home page or your profile page right? This kind of reminds me of the social experience provided by Facebook apps.
