I draw your attention to the tag reviews.
There is no tag description, and no usage guidance.
This looks like another classic "meta tag". It has no context without the other tags on a question and seems to be used for different things.
Currently, 7 questions with the tag:
- 2 are about reviews on Google+
- 1 is about simultaneously adding a photo to reviews on Foodspotting, Google Local, and Yelp
- 2 are about Amazon.com reviews
- 1 is a closed "help me find an app" question
- 1 is a "help me find an app" that's currently still open
