I really want to rate this 3.5 stars - don't think it's quite good enough for 4, but it's better than 3. The dystopian future is well portrayed and the satirical extrapolation of online culture is well done though heavy handed. Unfortunately there really aren't any likable characters in the book, so although I found it an interesting read, it was in a rather detached sense that never fully sucked me in. Still, I'd recommend it to anyone interested in the general subject area (dystopian futures and the direction of online culture such as Twitter).
