Google Personalized Recommendations: Should Local Review Sites be Afraid?

The Google Maps for Android 4.7 update brought a new feature and home page widget.

Personally Yours on the Go – Personalized Recommendations in Google Maps 4.7

Adding the new Google Maps rating widget to your home screen lets you quickly write reviews for places you visit. You can also share your ratings with friends using Google’s new Hotpot (not to be confused with a hotspot). Search results for rated places in Google Maps provides a Yelp-like local review summary. If you are using Hotpot, ratings from people you know show up in the search results too.

My quick set of searches revealed gaps in locations of well-known businesses like Starbucks. Google also couldn’t find my voting location recently. So, I have some doubts about how useful their local location information is for my area.
