Been meaning to mention this for a little while, the Knight Brothers 21st Century Challenge:
"Turn the web on its head. Show us how online news can help people improve their lives and shape their communities.
Knight Foundation is seeking new ideas, pilot projects, commercial products and leadership initiatives that will improve the flow of information and news in the public interest.
In 2007, we will award a total of $5 million to individuals, organizations or businesses that can show their ideas will transform community life."
Apply before December 31st with your great ideas...it looks very interesting for creative social inventor types out there (maybe the GIB should be applying?), particularly:
"Those who receive awards in this category must agree to share their ideas with others, further developing them publicly in a blog on a Knight-designated web site for at least a year.
The public would be encouraged to comment on the idea. The author would reply and nurture the discussion."
