Google said on Google+ that they are now randomly polling Google Maps app users when they are viewing a place listing about that place.
If you open the Google Maps app, search for a place to eat or hang out, Google may pop up a poll or a "riddle" as I think they are calling it.
The questions asked include:
- Is this place good for groups?
- Is this place popular for dinner?
I am sure there are many more questions but Google offers three answers, Yes, No or Not Sure.
