Another thought. I think it would be good to describe a couple of typical scenarios that A/B testing/content experiments could be used for. It might even make sense to then have the examples be written for one of the scenarios, so that it seems more real. Currently the examples are very artificial which can make it a little hard to make the leap to a realistic implementation.

I'd suggest talking to product to get some real world examples. @lou-wang, @shnayder, any suggestions?
