Illumio lets you search other people's brains

From Mercury News:

Imagine if you could search through the information in your colleagues' heads and uncover unknown areas of expertise and serendipitous connections -- like a mutual interest in organic gardening or open-source databases.

That's not a search you can do on Google. But it is one you can do thanks to the Internet and a free application called Illumio developed by Tacit Software of Palo Alto.

Illumio, which was released last month, is a new approach to the challenge of ``social search,'' finding information that other people know but haven't uploaded to a Web page.
