Chat with Google
Just add firstname.lastname@example.org to your MSN Messenger contact list, and you can chat to Google. From the site:
The idea behind Chat to Google is to add a chat interface to the knowledge contained in the Google search engine database. In theory, Google knows everything there is to know about any subject that has ever had something written about it on a website. That is a hell of a lot of knowledge. If you talk about something that the program doesn't know about then it simply searches for it on the web using Google and replies in a knowledgable fashion.
I'm waiting for the system to get online myself so I can try it out. It probably got pretty well pummeled by its mention on b3ta, but hopefully it won't die.
The thinking is that Google's page ranking system for yielding the most relevant results for a query make it a perfect filter for almost everything you could ask about. If you ask how Chat to Google feels, it will return a statement based on the most popular feelings in the internet right now. If everyone with a webpage said they were feeling ill, then Chat to Google would also claim to feel ill.
