content: Have you looked at the reviews of POIs around you? I did (on desktop, that is), and while there’s no or few feedback on places which aren’t frequented often (like pizza houses, bakeries, cafes, restaurants, bars, museums, universities, hairdressers…) yet, the other reviews from the span of last weeks actually are constructive by a huge margin. At least so far that you could use them as another data point on deciding to which of several competing places you want to go. Just as Mark Zuckerberg put it blunt, if you give people just the slightest incentive to hand over their data, they will. I don’t know what Google could gain through this other than trying to optimize their core business, advertisment.
