Reality TV leads to more memoirs?

Ever since James Frey's A Million Little Pieces, the memoir/fiction line has been scrutinized. You would think this would lead readers to be skeptical of memoirs but it seems to have had no negative effect on thier popularity. This article from CNN.com reports "Current memoirs in the top 10 of The New York Times' hardcover list include Julie Andrews' "Home," David Sheff's "Beautiful Boy," Jose Canseco's "Vindicated," Tori Spelling's "Stori Telling" and Valerie Bertinelli's "Losing It." The top two books on the Times' paperback nonfiction list are also memoirs -- Greg Mortenson and David Oliver Relin's "Three Cups of Tea" and Elizabeth Gilbert's "Eat, Pray, Love." Both have been on the Times list for more than a year." Even more interesting, "in 2007, more memoirs were accepted by publishers than debut novels, according to Michael Cader's Publishers Lunch newsletter, reported USA Today," a fact CNN connects to the popularity of reality TV.
If you click on the link for A Million Little Pieces, notice that while some Suffolk County Libraries kept the book in biography and some in non-fiction, other libraries moved it to fiction. I feel like a book labeled "biography" or "autobiography" is at one end of the "fact" spectrum, while a "fiction" book is at the opposite end. A "memoir" (the word is from the Latin memoria, meaning "memory") is a collection of the author's recollections. And we all know how reliable one's memory can be. "Memoirs" are somewhere between the two extreams of fiction/non-fiction.
