Looks like Amazon is discriminating against GLBT material when it comes to their ranking lists.
Authors such as Jaci Burton, Maya Banks, Larissa Ione and Stephanie Tyler have reported that since being stripped of their sales rankings, their titles are no longer found in searches on Amazon.com. MetaWriter is also compiling a list of titles that have been stripped of their sales rank.
When pressed for a reason, Amazon.com’s customer service department told YA author Mark Probst:In consideration of our entire customer base, we exclude “adult” material from appearing in some searches and best seller lists. Since these lists are generated using sales ranks, adult materials must also be excluded from that feature.
There's an ever growing list of books at Meta Writer of books not listed.

Me, I'm seriously disappointed in Amazon, but I'm sure the paltry amount of money I spend there wouldn't even be missed. Still, I won't be ordering from them for a while.
EDIT 9:58AM: I read that Amazon is calling it a "glitch" in the system. Of course it's a "glitch" that's been around since February.
