I didn't finish this, but it's interesting. If I'd read it at the right time it would definitely have been the best thing since sliced bread. Has a real Millennial Wheedonesque fanfic feel to it, and I certainly was around at the heyday of that particular vibe, but it lands way differently now, and the characters are insufferable and the story is uninteresting while the core part of the book, the ironic, smart-alec style, just seems to have aged out along with the blogging it valorises, and the cool tech definitely strikes an off note. Zombies versus Buffy's Scooby Gang? Noooooo. That isn't entirely the author's fault, of course, it was the zeitgeist, and she caught it, but I am anti-nostalgic for it, so that's on me.
