It is hard to be creative without some sort of stimuli. I suspect that encouraging ideas for improving society from a widely diverse base of experience and expertise - from every voter - may increase our chances of developing our country.
In the Interactive Democracy model, as ideas rise in popularity and become more widely publicised, related ideas may emerge from various sources, for consideration by parliament. This would require the "ideas engine" to be designed to allow "threads" to develop. Something that is easily achieved with a computerised system.
