Cory Doctorow.

A book released for free by the author, and recommended by Matthew when he started reading it in mid April 2010. However by May he'd retracted his recommendation. Decided not to read it. But - according to its Wikipedia page it's a transhumanist, postcyberpunk work, so maybe it's my sort of thing after all.
