The XX Factor: What women really think.

Ever Wanted To Look Inside Another Woman’s Checkbook?

I sure have. We all know how we're supposed to apportion our budget (10 percent into savings, no more than 30 percent towards housing, etc.), but how many of us really stick to that? And when we veer off course, what are the sirens pulling us away? I spend too much on cabs and Greek yogurt, for instance. This Mother Teresa figure drops $650 on dry-cleaning and a cool grand a week on skin-care.

So, to satisfy that voyeuristic impulse and perhaps do a little pop sociological research in the process, we're asking for XX Factor readers to participate in an experiment. We'd like to have a handful of women, from various parts of the country and occupying different income brackets, keep scrupulous track of their expenses for a week. We'll publish the results on Double X, the new Slate women's site that's launching in May. (We won't use your real name on the site, unless of course you want us to.) If you're interested in participating, send an email to DoubleX.slate@gmail.com with the subject line "Track My Spending," and we'll send along more details.
