INTERNET DATING MADNESS
When it comes to Internet dating, it's all about chemistry — even when you're creating a matchmaking site. Newsweek gives an account of how Gary Kremen went from barely affording $300 in rent to founding Match.com. (Success!) Meanwhile, Jezebel tears apart a "loathsome" dating site where women pay to date Harvard men. (Superficial failure... unless you're into that.) And a British dating site caters exclusively to people who "weren't blessed with great looks." (Success for all of the world's "great personalities"!) Still need help? The Morning News gives us a handy chart to help us determine who we can/cannot date. [Newsweek, Jezebel, UPI, The Morning News]

GIVING THE HOMELESS SOME CREDIT
A New York City ad executive was approached by a homeless man looking for change and she responded by giving him her AmEx card, which he then returned after spending $25 on deodorant and cigarettes. The story inspired a Canadian reporter to conduct an experiment in which he gave pre-paid credit cards to panhandlers asking for change, just to see if they would return the cards. The results are fascinating. [New York Post, The Star]

THE ROOT OF THE GREAT RECESSION
The story about how we dug ourselves into a financial mess has been told numerous times and involves names like Fannie, Freddie, Lehman, and AIG. The New Republic tells the story in a slightly different way: Rising income inequality between the haves and the have-nots led the U.S. government to help the have-nots afford new cars, vacations and houses by enhancing their access to credit. "Let them eat credit," was the mantra. So how do we fix income inequality? TNR has a suggestion, but executing it won't be so easy. [The New Republic]

MONEY AND TESTOSTERONE
We usually blame overly aggressive, brutish behavior (or suspicious numbers of home runs) on too much testosterone, but how does it affect our relationship with money? Scientific American reports on Swiss neuroscientists who designed a study that pumped the baseline levels of testosterone in women by 400 percent and asked them to play a game where they shared money. The result: Women who were given high levels of testosterone were more likely to play fairly and share their money evenly than women who were told they had been given testosterone but instead received placebos.

TRADER JOE'S SECRETS

We all know Trader Joe's as the hugely popular grocery store where employees wear Hawaiian shirts and the two-buck Chuck flows like water, but did you know that it's an $8 billion a year business owned by Germany's ultra-private Albecht family? Fortune magazine spent two months talking with suppliers and former execs to get inside Trader Joe's secret world, where a quirky, off-beat atmosphere is carefully cultivated, and a limited-selection, high-turnover business model creates obsessive and devoted customers. Bonus: Check out Fortune's video on the history of two-buck Chuck. [Fortune]
