I USE ADVICE from trustworthy sources so when I spotted TripAdvisor ratings as a swipe screen inside Here Maps on Lumia, I was impressed.
Some friends discount TripAdvisor and rely instead for wisdom from their slice of the Twitterverse. I personally prefer TripAdvisor because I have used it longer than any other review system and because I have found its information worthy of consideration. I'm happy to see it tightly integrated to Here Maps.
