Q&A added to business listings on Google Maps for Android, and mobile Search
Q&A is rolling out right now to Google Maps for Android and mobile Search
An update to Google Maps has added support for users to get involved in a Q&A section that will appear for certain business listings on Maps or mobile Search. Users will be able to ask questions, leave answers for existing questions, or 'upvote' a particularly good answer with a thumbs up.. Upvoted questions or answers get to go to the top of the line where they are more easily viewed by users.
