As my Twitter followers know, I open my weight on Twitter. Well, recently I tweet about my weight only. It effects my behavior a little. If it's getting up it's opened in an instant, so I came to take care my weigh more than before. Therefore, these tweets can naturally control my eating habits, because my scale automatically open my weight by using my twitter account. Activity using social networking like this scale will increase unbelievably. How we use it, that's the problem.
