Following celebrities on Twitter is the newest form of celebrity gossip, which itself is just a modern rendition of one of the most human of habits, gossip. Gossip is the human version of the grooming seen in other apes, and it is as much a part of the human condition as war. When everyone was uneducated and lived in small villages, as was the case for the majority of people until only a few hundred years ago, there was nothing to talk about except for gossip. Just because we now have more to talk about doesn't mean that the need for gossip has gone away completely.

Just because you and I don't get any value out of it doesn't mean that nobody else can.
