I'm glad this article exists, mainly because calling any and all optimization work a "micro-optimization" has become highly fashionable among the lazy. For every 1 developer who actually understands what Knuth was saying, there are 5 more who think that concern for performance during implementation is "premature", and will take any opportunity to criticize others, loudly, so that they appear intelligent. I recently had someone chastise me for micro-optimising, before even seeing the code, understanding the use-case, or knowing that my load-tests already established this as a bottleneck. I'd barely said more than "I'm looking for a more efficient implementation of this" before being shamed as a micro-optimizer. It's out of control.
