If you were eager to buy a book written by a guy who pretended to work at Goldman Sachs and maintained a popular Twitter account about pretending to ride in an elevator, some of it plagiarized, this will be disappointing: the book isn't happening.

Yesterday's Twitter niche bombshell was the alleged unmasking of @gselevator, a hugely popular "parody" account that recently landed itself a very real book deal. The fact that the jokes didn't really originate inside Goldman won't stop the deal—but how the fact that some of them didn't really originate with @gselevator?

The golden age of anonymous corporate elevator Twitter accounts is ending. It lasted about a week. After @CondeElevator closed down operations because "This got really crazy. Love my job," a series of knock-off elevator Twitter accounts launched. The only worthwhile one was @GSElevator, tweeting overheard conversations from Goldman Sachs branches the world around. According to Page Six, the company's notorious rigid management has "kicked off an internal probe" on the matter. After reportedly trying—and failing—to get Twitter to freeze the account, Goldman is now "investigating who is behind it. They believe it is an intern or a young gun, but there are enough facts on the feed for bosses to suspect it is someone with access inside the company."
