Modern Propaganda - Your Tax Dollars At Work

PSYOPS aka Psychological Warfare aka Information Manipulation is something that is actively being pursued by the American government, intelligence, and military institutions.  What is disturbing is not that it is being aimed at enemies.  It is that our allies are also being actively targetted.

Millions of dollars have been handed out in the form of government contracts for creating tens of thousands of websites and even cell phone edutainment games.

The real question is of course would any of this be truly effective in any way other than perhaps being construed as a spamming campaign / denial of service attack / watering-down of the accuracy of search engines and information sources?

Would this actually have any real effect beyond that which commercial enterprise has achieved so far?
