Citizens that are active and care, is what's necessary for democracy to work, that is, citizens which actively monitor, and participate in, political developments. Mere "informed voters" just voting once every 4-5 years do not really make democracy, even if we were to be generous and assume that the elections-very-X-years model and the existing representation hierarchies system are adequate.
Beyond that, for real democracy to work, the number one source of information of citizens should be real life experience with other citizens that they're actively learning from (their issues, grievances, etc with laws, political decisions, officials, etc) and collaborate with. Not the media.
In other words, voter who 99.9% of the time tend to their private affairs alone, can't make democracy work.
