If you understand Twitter and how to use it there can be a chance you're addicted to it. It's amazing how much information can actually fit into the space of 140 characters, and people who use the site have accepted this. But you may be using Twitter too much and research has shown that it may be harder to resist than cigarettes, alcohol, caffeine, sex and sleep. However I've found that being addicted to Twitter might not be a bad thing all the time. If you use Twitter for business and education, then what's wrong with being addicted to it? It means you thrive on the idea of learning something new and knowing stuff which other people don't.
