Aardvark allows you to ask questions, which then pushed the question out to a network of people who may be able to answer them. The answers are then sent back to you via instant message, email or even Twitter.
Aardvark was created by former Googlers and hasn’t taken on the traction that I expected early on.
Google has not yet confirmed the acquisition.
Postscript: Google sent me a statement confirming the acquisition. They said:
We have signed a definitive agreement to acquire Aardvark, but we don’t have any additional details to share right now.
As a first step, effective immediately, Aardvark will be available through Google Labs. Aardvark will remain fully operational and completely free, providing quick, helpful answers to all of your questions. You can sign up here.
As we move forward, we will continue working on Aardvark : improving its speed and quality, building exciting new features, responding to your feedback, and providing the highest level of support. Our top priority has been, and remains, providing a high-quality user experience.
