Spiggler is a web application that allows them to see on a Google map, the tweets that are being posted from the location where they are or in another city.
It is very interesting because it is showing the exact location from where the tweet was made and while it shows all that is published, it depends if users have enabled location, we can provide a lot of help.
I say it's interesting because for example we can know what is the trend in a particular city or what is being discussed at a given event.
When we ask if we permitted to use our geographic location and if we do, we will mark directly on the map where on around us and tweets are being posted in the sidebar to the right of the map is showing the text of those tweets.
In this column we can see the check-in of our friends on Facebook and FourSquare.
