Recommending the "errorlevel" blog
I've come across that blog.
I found most of the posts interesting.
This one is about the principles of propaganda.
"When I think about Karl Rove making talking points for Bush, this quote also comes to mind: “The most brilliant propagandist technique will yield no success unless one fundamental principle is borne in mind constantly…it must confine itself to a few points and repeat them over and over.” — Paul Joseph Goebbels, Nazi Propaganda Minister 1897-1945"
