Do you want to label foods with foreign DNA added from other plants, insects and animals (or even entirely created).
That would make sense. Instead the survey is for food containing any DNA, so Tomatos would always have to be labelled, even if there were no peanut genes........ that is, unless the Tomato were non-biological synthetic and sterile, to avoid having any DNA-containing surface bacteria.
Now all the Winklevoss twins need to do is find is a reason for the average American consumer to buy BTC and use them, instead of using credit cards and debit cards that are protected from fraud and loss by federal law. Bitcoin may be a great deal for businesses, but it is a terrible deal for consumers, and without people on both sides of the economic equation it is slowly dying (witness the long slow decline in price, and the fact that a few hundred thousand people at most possess all the BTC in circulation).
That's the crux of the problem, and the one that no one has figured out yet, beyond yelling "Those evil bankers and politicians are robbing you with fiat money!" Right, so I'll pay my percentage to the twins, instead of my local bank? That's like choosing to be eaten by jackals instead of wolves.
Presenting things as maps is the 21st century method of establishing credibility. It is much cheaper than actually creating an informative graphic with useful data, a la Edward Tufte.
As has been mentioned, this data is not all that useful. One still pretty much makes more money in places that are more expensive to live, but not nearly enough. For instance, in San Jose one might make 25% more than in Houston. On the other hand, the median price for a home in San Jose is 5 times the average pay listed on the site, while in Houston the median price for a home is only 1.4 times the average pay listed on the site. Doing this type of normalization is simple, but does not drive rubes to higher paying jobs that might pay higher commissions to places like Dice.
