I think we need some kind of explanation of what a content experiment is. In particular, I think we should use the terms A/B test and split test here, so that users understand that this is just our naming for this industry standard capability. Somehow we need to make it clear that edX supports A/B testing, but now that we've renamed it there's no way to see that from the index. I also did a search for "A/B test" and got no results. Using the term here would help people to find the feature.

Interestingly, there is a single match for "split test" because it finds the advanced module name of "split_test". :-)
