From the about text on the TID+ (Tomorrow I Decide+) demo site:
The TID+ Ideas system is an online application that lets you, as a citizen, post ideas, discuss them and show what you think by voting for or against them. The difference with a normal discussion forum is that this system is set up and monitored by the people who can take decisions based on your ideas. Once an idea is discussed and voted, no further action is needed – the idea will be sent to the authority that is competent to deal with your idea, and an answer will be provided.
The software is the result of a project, partly financed by the European Commission under the eParticipation preparatory framework.
