Amazing idea. I guess user interfaces for websites could follow a similar route some day. You specify the parameter range for the appearance of a website and the system finds the appropriate settings for a given demographic/geographic segment/time of day.
Hey guys, I wrote something called Genetify that is designed to be a general-purpose, unobtrusive way to optimize any kind of content on a web page for any arbitrary goal. Check it out at http://demo.genetify.com .
I really do want to make this into an open-source project for everyone. There a lot of cool optimizations you could do with a web page once a goal has been defined. If you are interested, could you post something at least indicating your support on John's blog? I think it will be the de facto place to discuss the open-sourcing of Genetify.
Actually, I have been thinking a lot on this idea. It is called adaptive web design. Cluttered web pages can be made a lot less cluttered by adaptively removing elements which are rarely used. Plus the system can also automatically test variations in designs, colours, etc depending on the user profile.
