Foursquare Tips & Forum
Foursquare Tips and Forum allows you to view Foursquare tips on a Google Map for any location. The map on first loading automatically detects your location and displays the Foursquare tips in your vicinity.
The map uses categorised map markers so, for example if you are looking for a restaurant, you can quickly browse through the Foursquare comments about restaurants in the area.
However, as well as being able to browse tips from Foursquare, you can also start a forum about any of the businesses or venues around a location. When you are reading a Foursqure tip on the map if you click on the forum icon (positioned next to the venue name) you can then open a forum about the venue / business and start a discussion.
