The Smarter Every Day YouTube channel is doing a series on platform manipulation

Some of the content is really basic, but he's put out several videos on it so far. He started with talking to a 4 star general who alluded to cyber and psychological warfare being at the forefront of modern conflict, and has done videos on Youtube and Twitter manipulation, and is doing one on facebook next. I'm really enjoying it so far. Curious if any of you have more in-depth looks at this, especially more technical ones.
