OK, I don't know what's up, maybe it's because it's Spring, but I've joined three social networks in the course of a week. sparkpeople, facebook, and imeem. It really makes me wonder about today's kids, with all this shallow socializing on these huge specialized networks! Imeem seems great for music and sparkpeople is interesting for health and facebook is just...well, facebook -- but if this is the way people socialize today, I'm really feeling old! How do you keep up with it? How do you resolve and determine REAL friendships? Or do you just use the online to supplement?
