I got an idea the last time I saw this discussed, which probably will make some present HN people rich: Bots which follow your own conversations/emails/etc, read the comments from other people -- and in another window suggest jokes, information, links etc based on parsed language. Just click to add the suggested answer. You could install modules to see suggestions from e.g. a stand up comedian, some experts for different topics or just the wikipedia pages for all mentioned non-trivial concepts, etc. A bot could e.g. help with fixing grammar errors. Everyone can be their own Woody Allen -- or get help to write as a depressive persona. Or as a Romeo. :-)
