Speed and scale (and reporting too, I guess) are very important considerations for data analysis.

But I wouldn't see Python as being speedier or better at scale and certainly not reporting. What are your speed up and scale advantages in Python over R. (Seriously interested)

Going R to Clojure or Julia seems like a gain but Python.

Sorry for delay. I think it's just better interoperability with many other systems. R has very hacked on interoperability in my opinion but I am not an expert.
