From the guide:
Which stations do you stop at for the best shopping, parks, restaurants, beaches, or entertainment? Can you run all of your after-work errands on the walk between your station and your house? Looking for a fun afternoon excursion or a new neighborhood to call home? The Train Stop Guide uses Walk Score and user ratings to help you figure out which stations are in the middle of walkable neighborhoods or near great attractions. Use the guide to learn what tips transit riders in other parts of the city have to share and to leave behind your own tips.
You can use the guide to rate how easy it is to get around without a car, and share knowledge about places around the stop that you may have visited.
