An IRC lets you chat away with other Net users. You can either join a discussion that is currently going on, or start a new one. Chat sessions are held in real time, and since people can join in from anywhere in the world, you can hear opinions from around the globe. You may even be able to talk with people who live close to a place where a certain major news event has taken place. You can react immediately to other people's comments and receive on-the-spot responses to your questions or ideas.
