I just finished reading Cory Doctorow's Locus Award-winning novelette When Sysadmins Ruled the Earth, which has been made freely available for all of us to read at Baen's Universe.
It's the first story I've read in ages that I read completely without stopping, and the first full-length story that I think I've ever read in its entirety online. Cory is one of the very few authors who inspire me as well as entertain me, because he tells great stories like this one.
