Great proposal re: http://data.gov from Sunlight Foundation
Check out this post Redesigning the Government: Data.gov:
"One thing we’ve been most excited about here at the Sunlight Foundation is the concept of Data.gov. Due later this year, new federal CIO Vivek Kundra will release a new central repository for government data and research.
And while in this series we traditionally re-design federal websites, we thought we’d actually take the opportunity to design data.gov right off the bat to show you all what we’d like to see happen." (from: from Sunlight Labs blog)
This is great! Instead of talking about it, actually showing some well thought out samples and sketches of how http://www.data.gov might actually work really makes the ideas come to life. If you are interested in government transparency, like I am, you should take a look at the proposals
