Spell: Summon External Memory

Someone, very recently, posted about a giveaway of a decent quantity of ARCs/bound galleys to bloggers who would agree to write about it. I have one of my very rare cool books coming up -- no, really, it's all about social networking and organizing online and bloggy kind of stuff; no accounting at all -- and I wanted to do something similar, but my Google skills are failing me this afternoon.

Does anyone out there remember, and could point me at, a similar recent declaration of "Bloggers! Free advance copies for all those who will write about it!"

Update: Thanks, folks! It probably was Little Brother that I was thinking about. (I had the vague sense that John Scalzi was involved, but Patrick is Scalzi's editor as well as Doctorow's, and just the kind of connection I'd expect my mind to make.) If anyone has any other recent examples, though, please let me know.

(Though, I seem to remember another recent book that was a "repost this message on your own blog to spread the word wider" -- that obviously wasn't Little Brother, because the combined force of Boing Boing and Making Light already threaten to swamp the Internet...)
