What little I know about it is mostly critical, but it appears to be far more of a motivational sermon supplier than any kind of practical education. I haven't been to a course so I won't hypothesize, but the media seems split on whether or not it has cult-like characteristics. My guess is its more like the movie, "Yes Man".
I'm a little annoyed at their usage of academic vernacular, but on the whole it doesn't seem like they're pretending to be something they're not. I'm un-inclined to participate, but I see no harm in checking it out.
