@hawkeye10,
I think that the Internet provides both "high quality news blogs" and complete drivel: vaccine scares, birther conspiracy theories, moon landing hoaxes, etc. Unfortunately, with a little effort both of these general categories look the same on your web page. Is that link a legitimate post discussing immigration or propaganda from a white supremacy site? The challenge for the average person who has limited time in their busy life is to figure out what is high quality and what is trash. IMO, this has led to a magnified ability to "tell the big lie." Now you can tell a lie and point to the Internet as support. Of course the Internet will also debunk your lie, but a quality debunking takes time while the Internet will repeat your lie a million times in a heartbeat. A perfect recent example is the plane that went down over Egypt. The Internet has loudly proclaimed that 1) it was an external explosion, 2) the pilot and plane were not at fault 3) ISIS did it as retaliation for Russia's actions in Syria. Of course buried in there somewhere is "no one has any data to support any of that" and "it takes very sophisticated weaponry to take out a plane five miles up", but who's reading that far down? I think that for those who want to research and understand issues, the Internet is a godsend. For those who only pay scant attention and skim the surface, the Internet is a source of confusing and sometimes intentionally misleading material that may foment rebellion, but more in the way a mob randomly destroys as opposed to a focused effort to improve the world.
