To the OP:
1) Turning our system into a voting system like it's American Idol not only would be a terribly inefficient method to do a worse job than the idiots do already, but it's susceptible to being crippled if there are techical difficulties and/or people manipulating the system. I think you're inviting as much or MORE corruption than there already is.
2/3)I'm sorry but by definition a democracy doesn't have many restrictions on who votes or how much say each person has. As far as "earning" the right to vote all people have to do right now is register when they're 18 years old and I would be willing to guess less than half even do that. I don't think you need to worry about a filtering system of voters - people already exclude themselves from the system just fine.
