"I really do believe that mayors have the political position to really change people's lives." — Eduardo Paes

What we are witnessing is the birth of something I call 'Polisdigitocracy.' This is a form of government that counts participation and transparency as its cornerstones and uses technology as its guide. The digital revolution is allowing democracy to recall its foundations and evolution is modernizing and reinforcing our fundamental values.

Rio will have to look after the legacy of infrastructure. But it's unclear who will run the sports centres after the Olympics.

There is no time and space limitation for public accountability on the Internet. Creative commonality is standard and does not resemble the authoritarian style of the dead communist experience. It seems that it is no longer society's obligation to understand legislation; it is a duty for governments to be understood by their people.

Hosting the Olympic Games of course guarantees the world's attention, but there is more to it than simply bathing in the global spotlight. Most importantly, host cities can use the opportunity to create a positive and lasting legacy, resulting in both tangible and intangible returns to local communities.
