Conde Nast’s anonymous Twitter feed @CondeElevator, which recounts musings overheard in the elevator of the company’s 4 Times Square headquarters, seems to have a bigger following than some of its magazines.

@CondeElevator, which has been the talk of the publishing giant since its launch on Saturday, has already gathered 45,000 Twitter followers, more than twice that for Conde’s Details (20,000) and approaching that of Allure (55,000) and Glamour (86,000).

“The online strategy of one rogue Conde employee seems better than that of some Conde magazines,” noted one high-ranking executive there. “How many magazines have built a Twitter following that fast before?”

In one post, Vogue Editor-in-Chief Anna Wintour was speaking with an assistant. (“VA: Blah blah Duke & Duchess of Windsor — AW: Cambridge. Duke & Duchess of CAMBRIDGE. VA: I’m sorry.”) A summer intern was quoted in another post, “My driver had SUCH a bad attitude. I was like, ‘Don’t complain to me, I didn’t eat lunch either! You think I eat clothes?’ ” There were also more mundane whispers: “Girl #1: Ewwww, it smells like McDonald’s in here.”

A delicious guessing game has begun as to who launched the Twitter feed, with followers anxiously waiting for dispatches from run-ins with famed Conde editors such as The New Yorker’s David Remnick and Vanity Fair’s Graydon Carter.

“The author is definitely someone who’s been in the building a lot and knows the culture,” mused one insider. Another suggested that the author, if caught, would likely be fired — so, “People are dying to find out, but they also don’t want to know much about it.”

A Conde Nast rep said: “While we’re curious about who or what might be behind the feed, we’re certainly not overly concerned. We’re flattered by the interest people have in daily life at Conde Nast.” Asked about the voracious online growth, the rep added: “We’re not comparing possible fictional accounts of elevator talk to actual brand editorial.”

UPDATE: The person behind the Twitter feed apparently quit today amid all the attention. “Girl or Guy #1 [in elevator alone]: This got really crazy. Love my job. Better stop. #sorry,” she or he wrote.
