I used the Google Answers (beta) yesterday. It worked like a charm. Excellent.
This is similar to asking a question on a weblog but without the financial incentive to provide a complete answer within a limited time frame.
Within an organizational context questions could be posted to a "question" specific category weblog, aggregated by a information expert via RSS, and posted to a "questions" weblog with answers. Readers of this weblog could extend the answers with comments and additional data. Questions, answers, and comments would then naturally become part of the firm's Intranet knowledge base. Despite appearances, search and information retrieval is difficult skill set to master. [John Robb's Radio Weblog]
I am not sure my organization is up to it, but it is an interesting approach to both capture data and allow it to be catalogued.
