This thread seems to be forgetting that Google Maps didn't just replace the atlas (for looking up names of things) and the dedicated GPS (for routing / directions), they also replaced the radar detector (OK that's Waze, but same people and same data), and the phone book.

I don't know about you, but I haven't bothered to look at any of the various "yellow pages" sites (to find a phone number or address), nor at Yelp (to find business reviews) in many years. And to make matters worse, I'm actually one of the volunteers feeding free labor / data to Maps, because I post reviews and make edits to business information. What can I say? They're really good at what they do.
