The other thing I'd point out is that the 'bid/ask' is similarly fictitious.  If, for example, I were to try and dump 200k shares at market right now, I'm fairly sure the price wouldn't suddenly drop to clear out all the published bids - one of the institutions would jump in and buy them up at .42 or .41.  Similarly, if I wanted to buy 200k, I doubt I could run the price up by bidding at market, suddenly 200k would become available at .43.
