This is a great example of how the ultimate execution will make all the difference. The Wall Street Journal today had a story about how new mobile phone services enable people to know where their friends are. The video gives a good overview of the service, and acknowledges the balance between privacy concerns and convenience.
This balance is very delicate. I'm not sure where I will fall on this one. I'm all for convenience, and I can easily see the benefits this service could provide. On the other hand, this certainly has the potential to be a bit too revealing for comfort. What do you think?
One conclusion drawn in the article amused me. They suspected that younger people would like the service. Sure. When it's their friends who can see them. What if this becomes a prerequisite for any parents who pay the cell phone bill?
