To choose the reliable information by reading comments in the internet

Once upon a time, we generally used to believe all contents in news supplied by mass media. However, recently we can decide whether we believe the information by reading comments about them from many people in the internet. Moreover, we can see the number of people who agree with an opinion by checking how many people contribute the same thinking in the internet. I think this is the next generation system of mass media. We make mass media by ourselves as shown by the name of "mass" media. This system prevents believing an opinion which is based on biased information supplied by only one medium. If we blindly believe a medium which has a strong power to agitate mass, this may cause terrible troubles including financial panics and wars. We will develop this next generation system to solve many problems which are based on confused information.
