Does anyone have a problem with the Voice of America broadcast?
Just wondering?
I thought of VOA too. I think the difference is that VOA broadcasts were clearly identified as such, and everyone knew it was Uncle Sam's version of things. Having sock puppets on social sites is more akin to having a mole work for an enemy's radio station, such as what happened in Kurt Vonnegut's book
Mother Night.
For sock puppets to work, though, it seems you would need to flood the internet with them. Fifty GS-5 government employees* clicking "I Like This!" on Facebook simply isn't going to do much.
*Come to think of it, they are probably CIA interns.
