post about shaping data to help debugging

I'd like to have feedback of any sort for this post on an experience I had debugging a nasty bug.

Obvious questions: 

* No images? This happened yesterday and I forgot to take screenshots. I thought of writing this article because I hit a second case of this 'shaping test data' today (again no screenshots) and thought it was worthy of mention.

review, maybe?: @benbjohnson @alexcoco @fbogsany
