Melissa Westbrook:

For entertainment value read the Discovering Math Q&A in this article in the Seattle Times. The Discovering Math guy (1) doesn’t always answer the question asked, (2) answers but doesn’t address the topic properly – see the question on if Discovering Math is “mathematically unsound” and (3) sounds like he works for the district.
Here’s one example:
The Discovering books have been criticized by parents, but they’ve been the top pick of a couple of districts in our area, including Seattle and Issaquah. Any thoughts on why the textbooks seem to be more popular with educators than with parents?
Ryan: I think because (parents) lack familiarity — this doesn’t look like what I was taught. I don’t know how you get students to a place where more is required of them by repeating things that have been done in the past. That’s not how we move forward in life.
What?
