Firstly, I find the reversal of roles from threads about the Tea Party to be interesting and really stupid. Oh, of course the Tea Party was full of a bunch of uneducated rubes who hypocritically bash some government spending while enjoying the fruits of some government spending in other areas that often have little or nothing to do with what they're bitching about. Now of course the Occupy movement is full of uneducated rubes who hypocritically bash some corporate actions while enjoying the fruits of some corporate actions in other areas that often have little or nothing to do with what they're bitching about. Many protestors are hypocritical, and many posters are consistent. However, more than a few aren't.
The movement is very broad. My center-left friend, fellow Libertarians, and myself were at Occupy DC, and all of us like a market-based economy and some big business. Many protestors are fed up with corporate welfare. Many want corporations (and capitalism for that matter) done away with entirely. There was a lot of great organization and poor organization, especially a very bizarre "general assembly" that I attended for a few minutes. The entire movement seems to be based on fighting corporate abuses in some way; of course many people see these abuses differently. What some might see as a problem with deregulation, others may see as a result of too much government intervention. Just like the Tea Party, some people are crazy; some know what they're talking about, but everybody is pissed off.
