Estonia is recognised as a beacon of E-Government achievement and is making strides in using technology to include citizens in democratic processes. The key to sustainable E-Participation is to ensure that all E-Participation initiatives contribute to establishing an overall community of Wikipedia-like users who believe that their commitment and investment of time really makes a difference. Over time, citizens’ roles and contributions may vary a lot, but this essential public infrastructure and policy has to be provided systematically for E-Participation to become a reality - whatever new technology comes along, and however successful individual projects are. This is the real meaning of sustainable E-Participation.
