-I would use it especially when I'm in a foreign town, in order to find some activities based on the population density.

-As suggestions:

->I would like an atmosphere feeling (comments about the activity or some photos)

->Also I would like to have a special identifier for my friends (that I added in this application)

->Maybe it would be nice if the application could add my location to facebook, and to let me tag friends from this application

->Maybe, in the future, I would like the activities to be categorized (music, movie, party, etc)
