I wanted to see if I could find more information about this - just found this note from Admin about this change:
------------------
I wanted to let you know you’ve stumbled upon one of our experiments.
In order to improve the listing page, we have to make changes. Every so often, we test changes on Etsy with a small number of people at random. If you see something different on the listing page right now, it might because you are in an experiment. Given their nature, we don't announce these tests and we can't help you get into them either -- doing so could skew our data.
Simply put: There is no better way to help us evaluate these changes than by testing them with actual Etsy visitors and members. This allows us to gather data and learn the impact of the change. Testing new approaches is a fairly common practice online and is used regularly by Google, Yahoo and Facebook.
Just because something launches as an experiment does not mean it will launch to everyone. Actually -- given their nature -- most will not. But all of the experiments are successful because they allow us to learn more about how people use Etsy. And in learning more about how people use Etsy, we can improve it.
Thanks,
Christopher
