A/B testing
Goof thread about A/B testing here:

Showing that A/B testing is now raising interest. You can download a simple class here which demonstrate that it is not that difficult to start A/B testing. this works like a banner rotator. but instead of rotating banners, you rotate CSS, and record conversions. Nothing really new.
You can download the class here.
Having said that now, this class is not "real" A/B testing - I have developed it just for the sake of the demonstration. If you wan to start doing some serious A/B testing, you'll have to make sure that the architecture of your site is robust, and can support this kind of things first (playing with CSS can bring some decent results - but if you want to start playing "safely" with your content, you'll have to move to xsl).
