The Tap Map
The Tap Map is an Irish website that utilises the power of the Twitter and Google Maps API's to visually display where people are drinking in Belfast. All a user needs to do is Tweet their drinking location from a bar in the city using their regular Twitter account and they will see themselves appear on an overall map of Belfast.
The Tap Map currently updates every hour (whilst in Beta). To add yourself to the map just Tweet @thetapmap and tag the name of the bar, for example #stiffkitten. Using the data provided by users The Tap Map is then able to provide a list of the current hottest places to drink in Belfast.
