Not everyone loves Oprah Winfrey, apparently.

The Register is taking the popular talk show host to task for her half-hearted endorsement of's (NASDAQ:AMZN) Kindle.

It was back in October when Winfrey dedicated an entire show to singing the Kindle's praises. "It's absolutely my new favorite favorite thing in the world," she told her audience.

However, according to The Register, less than half of her monthly book club recommendations are presently available for the e-book reader. Winfrey magazines O and O at Home also aren't available for the Kindle.

Personally, I can see why glossy magazines would sidestep the platform. The Kindle isn't kind to graphical publications. However, one would think that Winfrey would be cashing in on the audience that she has herded toward the nascent reader via every possible angle.

Winfrey isn't the only one that's blowing it. Amazon itself is still at least a month away from restocking its store with new Kindle readers. The online retailer has been out of stock since November, missing out on the critical holiday shopping season.

The supply void may be good news for Sony's (NYSE:SNE) rival device or stirring up Kindle resale demand on eBay (NASDAQ:EBAY), but the likely explanation is that Amazon is simply making way for the next generation of Kindle. It would be a shock to see the same old Kindle return in late February or early March after a three-month outage.

Maybe that's what Winfrey is waiting for before giving her "favorite favorite" gadget more support. Maybe the new Kindle will serve up the enhancements to make digital delivery fitting for even the most colorful of magazines. It will be then that local booksellers like Barnes & Noble (NYSE:BKS), Books-A-Million (NASDAQ:BAMM), and Borders (NYSE:BGP) will be doomed.

Amazon and Winfrey can be blamed for the lousy timing of the endorsement, but "better early than never" is what I would say.
