Below is a picture of what seems to be a very nice bathroom scale.
When you step on the scale (called an Aria Wi-Fi Smart Scale), the WiFi functionality of the scale can send and post your weight on Facebook or Twitter as your status to your friends or followers. If you set it up properly, every time you weigh yourself, your weight can be posted.
I do thoroughly enjoy social media like Facebook and Twitter and will, in most cases, defend it.
However, I say this with emphasis: WHO WOULD WANT THIS SCALE?
