Whether you're actively browsing through Field Trip's listings or waiting for it to push out notifications, you're going to get mixed results, as far as interesting posts go. One the one hand, I found tons of interesting and useful information about restaurants, concerts, local art installations, and architectural marvels nearby. But on the other hand, much of that useful information was sprinkled between completely irrelevant and useless listings. For instance, I got a notification for a small event that occurred near my location more than two years ago. Also, I saw more than a few posts about seemingly random events throughout history. The good thing is that Field Trip lets you help calibrate its recommendations. You can vote cards up or down, and even change the settings for individual publications. This is something you absolutely must do in order to improve your experience.
Overall, I am impressed with Field Trip. It's beautifully designed, and relatively easy to use. Plus, it comes with a great assortment of content partners and nifty features like text-to-speech, which can read your cards aloud. While it still has a lot of work to do as far as calibrating its recommendations, I do think it can be a fun source of interesting information, especially for curious tourists. That said, it's certainly not a necessity for local explorers at this point. However, considering Google's well-documented interest in local search, you can bet the company will put the work in and show us some massive improvements in the next version.
