The Digital Skeptic's Guide to 3 Wall Street Slayers

NEW YORK (MainStreet) -- The digital barbarians are rattling the gate.

With Goldman Sachs ( GC), JPMorgan Chase ( JPM) and Morgan Stanley ( MS) charging probably $150 million in fees to lower the IPO drawbridge for a young, cash-starved CEO named Mark Zuckerberg, it almost feels like the invulnerable Wall Street fortress of yesteryear, doesn't it?

But be honest, it's just all like the guards at Buckingham Palace -- a nice little show for the tourists.

BlackRock ( BLK), probably the world's largest money manager, summarily dumped the supposed invulnerable trading czar, Goldman Sachs, to begin dealing on its own.

So-called dark pools -- which are nothing more than a geek who matches buyers and sellers with a PC under his desk -- are where the real growth in finance is. Volume for these trading riffs on Napster hit an all-time high this year, according to Rosenblatt Securities, which tracks the dark trend of dark pools.
