Or read John Resig's (JQuery) nice intro: http://ejohn.org/blog/genetic-ab-testing-with-javascript/
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.
My idea was to make a javascript library which when included would automatically analyze the page structure and make the pages adaptive without much of an effort from the developer. The only thing here is that heavy javascript processing would be required to modify pages on the fly. Or, this can also be done on the backend but that would require templatizing existing websites (which could further slow down adoption of this technique).
Any thoughts?
