Mark Zuckerberg has something up his sleeves for November 6th, but he's keeping whatever it is under the table until then. Facebook sent advertisers and agencies in New York a little invitation in the form of a Lucite brick: "You are invited to a discussion with Mark Zuckerberg and the Facebook executive team as we unveil a new way of advertising online." There's a big rumor that all the de-classified information you provide on Facebook will be available to advertisers. Already, nine companies -- Apple, CBS, Chase, Coke, Condé Nast, General Motors, Nike, Sony, and Verizon -- have jumped on board and will pay at least $300,000 each to be "Landmark Partners". Another rumor is that, somehow, Facebook will be able to target non-Facebook users on other sites. Internet marketers salivate as the countdown begins.
