Twitter Scale - Tweet Your Weight, Shed Pounds?

First there was a scale that uploads you current weight to your computer. Then there was the phenomenon of tweeting what you eat. Now technologically-savvy slimmers can take it a step further by tweeting their weight with this high-tech WiFi scale -- it automatically updates your latest weigh-in on twitter for all your followers to see. But it does more than that -- it also calculates your BMI and body fat, all for the price of $159.

I know what you're thinking: Why on earth would anyone want to post their weight on twitter? Withings, the French company behind this product, thinks that tweeting your weight will provide a you with a much-needed kick in the butt, "further motivating them by sharing their progress with followers," reported the LA Times. In other words, they want to shame you into sticking to your diet. It's a good concept in theory, but I have my doubts that this kind of 'shame' diet actually works.

What's your take? Would having your weight published on twitter motivate you or embarrass you horribly?
