I think this online database has been a quiet revolution.
It helps us understand our history through numbers.
It is very often with surprised that we realise how the rest of us live and i think that for some, social impact will start here.
Some TED talks have been of great inspiration to me and i always want to share the special ones. Maybe next time on a taxi i'll try my piece of sharing and see if it goes on. thanks Antonio! i loved it.
