Remember George magazine? The celebrities meet politics magazine that made a huge splash, lasted a couple of years, and then quietly died? Jim Geraghty says that Arianna Huffington's new "celebrity collective blogging" venture "has 'Tina Brown's Talk magazine' or 'John F. Kennedy Jr.'s George magazine' written all over it--and he's preparing to "savor the impending schadenfreude":

Let me offer a theory on why blogs took off: Many of the best were written by folks who were either A) professional writers who wanted to write in a non-article or column form (Mickey Kaus, Andrew Sullivan, the Corner gang) B) lawyers/law professors who are used to persuading the public (the Powerline guys, Glenn Reynolds, Volokh, Hugh Hewitt) or C) interesting people who happen to be insightful/funny/great writers (Steven Den Beste, Stephen Green, Amy Welborn).

You notice few of those folks are celebrities in their own right — or at least, they don't already have a format to offer their thoughts/analysis/reporting on a regular basis.

If I want to know what Walter Cronkite thinks, sooner or later some journalism magazine will ask him. Warren Beatty, the millionaire who endorses socialism, can tell me what he thinks in movies or in one of his endless glossy magazine profiles. David Mamet gets whole plays to tell the world what he thinks.

Attention, Arianna: We already know what celebrities think. They're telling us all the time. Large chunks of the mainstream media are devoted to telling us the latest political and philosophical breakthroughs they want to share with the world. I suspect people turn to blogs because they want something different.

This project, in short, adds to an already huge supply, in a market for which the demand is limited... perhaps exhausted.
