Clearly a man who has never spent time on a boat. If you ever want to find out why Twitter is irrelevent, learn how to sail and disconnect for a week. You will learn a lot about how meaningless Twitter is once you disconnect from email/phone/internet/tv/radio for a week and feel incredibly liberated. If you want to find an idea that will change the world, disconnect from it all for a short period. When you come back the first thing you will do is cancel your Twitter, aim, etc and the next thing you will do is start doing something meaningful to more people than just those who are plugged into the net 24 hours a day.
