The Government Information Awareness project is intended to bring transparency to politically and socially relevent information. A major idea is to allow users to post and contest unchecked information while retaining anonymity. It involves some really hard information architecture issues.
The inspiration came from a plot to collect and relate info on US citizens, by a man convicted of attempting to run a shadow government. That man is Admiral John Poindexter, and his Total Information Awareness plot has actually been implemented as the the more marketable Terrorism Information Awareness program.
I haven’t heard about GIA since its launch. I’m not sure if this is an interesting experiment that didn’t pan out, or if the idea could have legs.
