I don't know if my vote matters, but I will give anyway.
Totally +1 for this. Reasons:
It *doesn't* need Facebook and/or Foursquare account to be useful; it *is* useful itself. It doesn't have the same functionalities that other preinstalled app. It have the same UI pattern (GNOME/GTK3/HeaderBar/etc) that many other preinstalled apps. Is just 329k. It is a (great) FOSS alternative to (unfortunately) widely used proprietary apps/services. *And* people will probably use it (or use it more) if it become more exposed.
