I am surprised by all the negative commentary here. On the whole, companies like Optimizely, RJMetrics, Custora, and others are doing more to push statistical analysis to the mass market than anyone else. These tools are not designed for statisticians or ML practitioners so it makes sense they do not put language like Bayesian, etc. front and center. IMO, the more people using data to make decisions, the better.

Why is it their best product? Applying an idea at scale is strategic, not necessarily innovative. For example:
- Bloomspot's $40M raise and accompanying shift in focus (http://www.bloomspot.com/media/assets/Bloomspot_Marketing_Ki...)
- Swipely, Offermatic, etc.
- GRS, a vendor of this data (http://www.grsgroup.com/)
- Also, dozens of similar ideas such as Amex using FB data: http://www.forbes.com/sites/moneybuilder/2011/07/20/link-lik...
The pricing on this is not particularly attractive to merchants, especially small ones.
