text: website that tracks which councils have published public toilet open data, and which have not. A 
  
  map like this solves one specific, concrete problem in the ordinary, daily life of many people: 
  
  *"Many older people have continence concerns and only go to places where they know there is a*
  
  *toilet. "*
  
  It is also possible and useful to pass the message that, when it comes to participation, activism and 
  
  transparency in politics, Open Data are a concrete and pacific weapon that is both very effective and 
  
  very easy to use for everybody. Dino Amenduni explained the first point well at the end of 2010 
  
  with words and arguments that, while tightly bound to the current situation in Italy, apply, in spirit, 
  
  also to other countries: 
  
  *in order to have your voice heard, it is necessary to threaten the private interests of*
  *politicians. The ways to achieve this goal are, in my opinion... Communication*
  *guerrilla: physical violence doesn't generate change anymore. Power is in the hands of*
  *those who have data. But those data must be communicated, made usable, fun to use,*
  *shareable, in order to give the feeling that knowledge brings a concrete (economic or*
  *intangible) personal advantage*
