I recently discovered Cory Doctorow. Apparently he's pretty well known. I had never heard of him until I stumbled upon some of his writings in searching for articles related to a paper I was writing. Of course, I ended up reading a bunch of his stuff instead of what I needed for my paper.
He has a fun story called Scroogled where he pictures a world in which Google turns evil.
I haven't gotten to it yet, but I'm looking forward to reading his When Sysadmins Ruled the Earth, when I get a minute.
