"Elimination communication" — babies without diapers — "is finding an audience in the hipper precincts of New York City."

"Ms. Shapiro, who is a doula, a birth and child-rearing coach, says it is practically now a job qualification to at least be able to offer diaper-free training as an option to clients. Caribou Baby, an 'eco-friendly maternity, baby and lifestyle store' on the border of artsy Greenpoint and Williamsburg, has been drawing capacity crowds to its diaper-free 'Meetups,' where parents exchange tips like how to get a baby to urinate on the street between parked cars."

It's Earth Day, baby. Catch up with the hipsters! Get cracking! Or do you not even know what a doula is? Well? Do you or don't you? Do you doo doo with a doula?

If you had to choose a dimension within which to aspire toward hipness, would you choose poop? Perhaps there's something especially hip about expressing lofty aspirations in the lowliest medium.
