Inevitably, Interactive Democracy will be inundated by half baked ideas from amateurs. This isn't necessarily a bad thing because off-the-wall suggestions may inspire others to write their own, better informed, Petitions. In this way the ePetition system may act like an enormous brainstorming system. (One of the rules of brainstorming is that any idea should be recorded without criticism, as it may inspire other, better ideas.)
Crazy ideas are unlikely to garner sufficient support to be put before parliament, but even if they were, our elected politicians must debate them, look at the counter arguments and associated issues, and form realistic and workable choices to put before voters.
