Some ideas knocking around at the moment of having anything that raises enough petition signatures (online presumably) would then get debated in parliament.
I'm not sure about this one. How would it be controlled and policed, for one? Given that one of the biggest popular movements this year was a FB campaign to hero worship murderer Raoul Moat, the potential for mischief is quite large. And whatever happened to leadership?... Focus grouping may have its place in other areas but I'm not sure it's the way to govern a country.
