It's interesting to see that this is only active thread I could find in the forum that talked about the price disparity between Gox and BitStamp.

Right now there is a 9% difference in the price at Gox ($107) versus BitStamp ($98).  This has been ongoing for the last few days now, and in past weeks as well.

I'm intrigued; variances like this would never last this long in a mature market.
