In a voicemail to Om Malik yesterday I observed that these things are not chatbots. I don't like the word chat. They have a chat-derived UI, true, but I find I go there when I have a question, much like I go to a search engine. It's a way to search a database that's also capable of writing. I'm looking for docs that might not exist, if so the software will try to create it for us. Much more useful than Google. As much of an advance over Google as Google was over Yahoo's directory.
