Well, I enjoyed it, but I'm into that sort of thing. The main female protagonist has a few quirks more suited for a fanfic than an actual story you pay cash money for, but it doesn't end up coming off as too bad-- mainly, they just hammer on the inconvenience of it all a bit too often. The attitudes in the book and the general tone make it clear that this was written by one of sci-fi's new kids, sometimes almost reminding me of something out of cyberpunk for the role bloggers and the new media take, and it often reads less like a zombie novel than a post-zombie novel, or even a thriller.
It's one of those books that definitely reads like the author had a trilogy mapped out and needed to get a few things out of the way before she could really launch into what she wanted to do, too, so if that's a turnoff, consider yourself turned off. It's not at all uninteresting, though. She does a great job of building up this world, and you get a lot of detail on the post-outbreak society that a lot of other authors would handwave or overlook.
