I care about it in the sense that it's a privacy nightmare. That's why I don't use it. They are getting people to voluntarily do what they couldn't compel them to do through legislative means: build dossiers on themselves and submit them to a corporation; and thanks to recent anti-terror acts of dubious constitutionality, government will be able to look at that information when they want to. Combine with Twitter for play-by-play of your whereabouts and actions, and Loopt to geolocate you everywhere you go. It's a surveillance society that the innocent invited upon themselves uncynically.
