Stage 1 tweetphilia- Mild. Update what you are doing maybe 5-10 times a day.
stage 2 tweetphilia- Moderate. Not only updating what you are up to, but having conversations in your tweeting and telling everyone how you feel about something. You also have your twitter updates on your myspace/facebook/ect. account.
stage 3 tweetphilia- extreme. Updating everything you do. Updating anything that comes to your mind. Using any possible way to tweet- including from your phone. You have downloaded a twitter app such as TweetDeck to update from. You are addicted. Seek help.
