Note: All ratings are my initial personal opinions of the quality of the Web sites, nothing more.
Also: if I didn't think the sites were good, they wouldn't be here. So, one star isn't bad, it's just at the low end of "good enough to link."

Fat fingered typing costs a trader's bosses £128m *** News Story: Units can be extremely important: "He wanted to sell one share in a new telecoms company called J Com, for 600,000 yen (about £3,000). Unfortunately, the order went through as a sale of 600,000 shares at 1 yen each.... Despite Mizuho's attempts to rectify the mistake, some estimates put the possible financial damage to the firm at about 60 billion yen -- a figure that may be big enough to destabilise the securities arm of what is one of the four largest financial groups in the world."
