With Velvet Revolver’s future uncertain, guitarist Duff McKagan, already a columnist for Seattle Weekly, will share his advice about all things business with the readers of Playboy.com as the site’s new financial columnist. “How the hell is it that I will to be writing about money matters for Playboy?” Duff asks rhetorically in the Seattle Weekly. “Well, over the last few years, I have been doing more and more TV and print interviews regarding some faction of finance. It started in 2004 when a writer for some music newspaper asked me about my experience going to business-school after my career with Gn’R.”

And just to show he means business, McKagan even name-checks Adam Smith, “the founder of capitalism.” “I do find how money works rather fascinating,” McKagan writes. “I think part of my mission statement for Playboy may be to perhaps try and shed some light and maybe even bring down some of the criminals on Wall St. Wouldn’t that be cool? Maybe be a voice for the people — one that can’t be bought (well, no one has ever actually tried to bribe me, but I’ll let you know if they do!).”

While McKagan does seem to be business-savvy, let’s face facts here: We don’t know the difference between a cerebrum and a cerebellum, but we could probably author a column on brain surgery for Playboy.com, because nobody who actually visits Playboy.com will be interested in brain surgery or finance or anything else unrelated to the main reason why people visit Playboy.com, and that’s naked women. Duff could write a column that single-handedly fixes the entire economy and it would probably go unnoticed there for months unless it was surrounded by pictures of The Girls Next Door. Despite his new job, McKagan will continue to write columns for the Seattle Weekly, whose writing staff also includes Nirvana bassist Krist Novoselic.
