Google has named Larry Brilliant as Executive Director of Google.org. The official press release can be found here. I guess this puts to rest any speculation that Google.org is closing up shop based on a statement they made in their Q4 earnings report.
"As Larry Page and I have said, we hope that the contributions of Google.org may someday exceed those of Google itself in terms of overall world impact by ambitiously applying innovation and significant resources to the largest of the world's problems," said Google co-founder Sergey Brin. "Today we are excited to announce that we have found a leader that embodies that goal in spirit and in accomplishments – Larry Brilliant."
"I'm deeply honored to have been selected to direct Google.org," said Dr. Brilliant. "I have great admiration for Google's technical contributions to society and believe that it can make have an equally great impression through philanthropy." -- via press release
