First, we're actively working on improving page load times.
Second, having discovered issues with algorithmic complexity makes me question claims that they are not important for day to day work. What do you think?
Algorithmic complexity is certainly important. Intuition and knowledge of (or ability to research) the pros and cons of existing algorithms are essential. However, I don't think you need to see a single line of code (on a whiteboard or not) in order to test for that.
