The researchers found that even small internet outlets such as Truthout, Ms., Yes!, etc, can have a very significant influence on people's attention in their communications as measured by Twitter.
You can see the reasons for doing this kind of research: to further refine how corporate media corporations shape news events. This has been common knowledge for many decades. That is precisely why our capitalist masters like to invest in major media even though they are by and large not profitable. It's because major media corporations are powerful in shaping news and opinions of the general public which always ends up supporting the interests of the tiny ruling class of capitalists in opposition to the general interest. This is precisely why Jeff Bezos (Amazon corporation) bought The Washington Post. Our ruling class already know this, and they've known it for many years. The tip-off is suggested in the concluding naive questions:
If mostly small publishers working in small collaborations can influence conversation so significantly, what of non-profit news collaborations, local newspapers, and television news? What of collaborations between all three?Of course, you and most of the people who follow this blog know that major media have for a number of years collaborated to dumb-down, mislead, and deceive the general public. The challenging implication from this is that we, the people, must find a way to establish our own media. Otherwise we will continue on down the road of ignorance and deception while capitalists, because of their addictions to profits and power, will destroy all of humanity.
The ruling class controls every institution to insure that they serve their interests. As a way of illustration to demonstrate this insight, I recommend reading "How Hollywood sold us the (good) Korean War" by Patrice Greanville. This very popular TV series (M*A*S*H) sold imperialism as entertainment to the gullible American people.
