I've been going through the Drupal.org Customizations list.
Realized with many of the changes it would to be able to evaluate with some sort of AB testing.
It would be really good to have measurable results for various changes so that we can actually test what the impact of the is.
But since most of the behavior I'm interested in testing is of our user community, we could also simply do even/odd on user ID's for most elements.
Whichever we choose, we need access to data about how this affects user behavior.
We've got to have dozens of folks in this community with a bunch of experience in building these. Who could we engage?
