Dan, one of my co-workers, sent me this article titled Encarta access through IM.  Apparently, you add encarta@conversagent.com to MSN Messenger as a contact (FYI: I use Trillian and it works) and start asking questions.  It gives you a few examples:

* What is the size of Canada?
* Where was Leonardo da Vinci born?
* What is a cello?

So here's my quick conversation with encarta:

[10:22] John: what is a wiki?
[10:22] Encarta® Instant Answers: I am sorry, I couldn't find any definition or article relevant to this subject.  Please try asking me another way, or type "?" to see examples of questions I can answer.
[10:23] John: what the fuck?
[10:23] Encarta® Instant Answers: Is that language necessary?

The screen cap is better:



Apparently encarta doesn't like it rough. 

Please post any other strange responses or questions that return odd responses.  I could do this all day...
