Art, don't get too worked up. Just different marketplaces with a different take on the value of Tyhee. Given a successful company (which we all hope for) a share on one exchange will be worth a share on the other eventually. What will happen if the company gets big enough and lower "risk" (from Pinks to Amex?) is that the arbitrage desks at brokers will start playing the differences of the two shares for profit. I've noticed the shares on the German exchange are often a bargain, but haven't bought because commissions are higher and liquidity doesn't appear to be as good.
BTW Baires, I appreciate the questions you ask Webb, too. Thanks.
