Maybe it's the "gossip" in all of us that makes us do it? Face it, watching reality tv and then posting your opinion on a site like this is better than watching out your front window to see who is doing what (whom) and then getting together with a group of your neighbors and dishing the dirt. Human nature makes us interested in other people and their reactions to various events and obstacles. As a species, we've been doing it for centuries, this is just the latest way of expanding our "gossip-fest".
