wjk,
yes - that is what I see too. There is so much "filtering" on what is reported. On one side it's understandable - as the sources for news and information are just overwhelming nowadays. That makes it almost necessary to have some form of higher commentary/analysis that helps get through the processing of the news. That again leaves more room for bias, and not just reporting straight facts. Keeping to just the facts goes back to the filtering again.
I think that we ultimately need to trust those who supply us with the news. This is naturally someone who "thinks like we think". Ultimately that will shut us out and divide us into groups with stronger opinions diverging from people having other sources. However, we cannot cover all the bases, all aspects and consider every side on every news item.
There needs to be some balance, and we need the challenge - meet other opinions. It doesn't cut it to be lazy, isolate oneself from news or other opinions you don't agree with - because ultimately you are called upon to take informed decisions and be part of democracy. Democracy demands some effort, work and being an active informed participant - if not you undermine the very mechanics of democracy - to some point.
I think we need the support of technology to keep us balanced in how we interact in democracies, just as we use technology to get more news - or any news for that matter. What I mean is that there are more forms of interacting in more structured ways that are more constructive and helpful in a democracy - not these simplified ways that just mimic how we would interact in any crowd/gathering with those yelling loudest or making a fuzz are the ones who get their way. Intelligent, structured and balanced interaction - where technology is a tool taking the interaction to a more effective level. The trust issue is then shifted more from the source to the technology and model. If we can trust the model, the fundamental mathematics/mechanics and philosophy behind the technology - then we can rely more on fair interaction and participating in more effective manners to democracy.
I am a strong supporter of things like e-democracy and representative direct democracy as a transition to direct democracy. I think getting rid of "politicians", "political parties", de facto oligarchy and nepotism - and having democratic models that we trust in place for these - this is how democracy should evolve. There are tons of research papers on how to avoid electronic voting fraud etc. on Citeseer, and in crisis situations it's always possible to have elected counsels who will "be on watch" for a given term as backup solutions. Interaction points can be spread to ATMs, gas stations etc. Every practical problem can be overcome, and that makes e-democracy a possibility.
It is possible to have something like representative direct democracy and de facto e-democracy already today. In some countries they already have started - and I do think it's the future. Plain and simple discussion forums like this one or simple polls are not effective in withstanding sabotaging from single disruptive agents or organized sabotage. But there are models for avoiding the pitfalls and getting stronger structures that also cater for defending against attacks. I do not favour exclusion - but think that the design of models should be such that attacks are not effective - nullifying them. That means deflecting attacks on the model, service and functionality itself - not the opinions expressed. One of the cornerstones is having the best possible identification scheme - which needs to be at least as good as the identification used in today's voting systems - but preferably a better identification scheme.
I also see that the news gathering itself will change from the funneled journalism from news organizations into more user contributed content, and merit-/trust-based systems. That does not mean that organized news or journalists would be unnecessary, they would just contribute differently - and into a more balanced model where the main trust lies with the democratic model - where news and information is a central piece we need to protect - since our informed participation is the central piece in any democracy.
Some might say "it's nuts" to think about progress and such profound changes which lies quite some time ahead, but actually some of these changes are completely doable even today. For a trustworthy and robust interaction, information and voting platform - that has not been fully researched nor attempted - yet...
