37signals: A/B testing part 3: Finalé
I would love to see the data sets that support the lifts - those little "up 3.49 / down 3.38" can get notoriously tricky in terms of statistical relevancy using GWO or otherwise.<p>Also to note, I often find that radical new variant designs for well established clients have rapidly diminishing returns.<p>Sometimes the sheer "newness" can skew the data as folks sitting on the fence (returning visitors) push the convo data up.<p>All that said, I'm a fan of the new look and feel, fun to watch 37signals influence turn the market - expect to see lots of similar looking stuff in the future.
