Via doors of perception :
The average teenage girl in Japan spends, or charges to her pliant parents, a hefty $300 a month. A significant minority spends far more. The money goes about equally on three things: food; fashion & beauty products; and the mobile phone. According to investor and moblogging eminence Joi Ito, when a sample of these girls was asked where they would cut back if – heaven forbid – their paltry allowance were to be reduced, a large majority said food would go first, then fashion, and phone calls (and now moblogging) last.
