This is the coolest thing I've seen in the last five minutes.  I stumbled across this post.  Just add encarta@conversagent.com as a contact in MSN messenger and start asking questions. 

I couldn't resist having a little fun.  The interactive content from the chat session isn't displayed here, but that's not important.  Check out the nice little talk I had:

I do enjoy the conversation, but what I'm really here for is 
to help you learn new things. What does the flag of Venezuela 
look like?  Ask me, and I might even play its national anthem 
too.

Mike Hodnick says:
If you can't solve a quadratic equation, how the hell can you 
tell me what a flag looks like?

Encarta® Instant Answers says:
I'm afraid I won't be able to find anything about this in 
the encyclopedia.
Type "?" any time for examples of questions you can ask me.

Dumbass
