This is why you shouldn't read Andrew Breitbart's websites. Look at the names on that list. Dylan Ratigan and Matt Taibbi are political pundits long known to have very similar views to the OWS people. The only other thing that link has is the mere mention of the names of other... you guessed it... opinion people. The only exception to that is Bill Moyers, and the article itself admits that it has no evidence of his involvement. My question would be why you would think political pundits WOULDN'T be on those lists? Would you consider there to be a scandal if Sean Hannity is on a Tea Party mailing list? (he's probably on a bunch).
This is a common deception from Breitbart's sites, btw. They are simply not reputable sources.
