Wes, there needs to be a great book about Pandas as it's an amazing tool, and you've written it. But Data Analysis is a HUGE subject and passively implying that it can only be tackled with Pandas is misleading. My post was intended to be a snark at O'Reilly's general failing quality - I'm sorry if I put your nose out of joint.
I do data analysis and pandas is a huge part of that. He can't usefully write about the whole universe of data analysis. The part he wrote about is definitely quite relevant.
