I think you are absolutely wrong, just because of who writes the post. Minutes prior to reading this post, i was looking at Kaggle ( datasets and some competitions), for statistic analysis.

Mehul Patel ( who wrote this post), was COO at Kaggle ( i must admit, this is a unbelievable coincidence)

I think that someone who worked at Kaggle can get pretty accurate results from datasets. I think referring this as "just a blog post" severly ignores the effort that has been put into it.
