I think one of the biggest problem in our country is the media monopoly that gets 300 million people thinking about the exact same issue that Glenn Beck or Hannity is promoting.
Google and Yahoo have done an excellent job at creating a webpage where people can read the latest news. But obviously, they work the exact same way as the right wing media, only showing news that make republicans look good and democrats look bad and don't show absolutely anything progressive except for something negative.
If somebody could come up with something similar to Google News or Yahoo News where people can go and read the main news of the day without the ridiculous right wing bias. I think it would make a huge difference in our society (if it's successful)
