I. FRONT AND CENTER
---------------------
1. Don't Blame the Browser
Melih Abdulhayoglu
There was a time when most diseases were fatal for humans. Intense study and research helped doctors manage diseases better, and subsequently even prevent them altogether.

2. Resurrecting the Killfile
By Oliver Day
In William Gibson's Idoru, one of the book's hackers describes a community of people who all share a file of unwanted things to create the walled city of Hak Nam. "They made something like a killfile of everything, everything they didn't like, and they turned that inside out," he wrote.
