I feel like a lot of productivity advice comes from people who are extreme outliers when it comes to motivation and this is a prime example of that.
For example, learn as much as possible about the domain and stack you are working in or read books about fundamentals rather than blogs because books provide information in condensed form and are best suited to topics that change slowly, if ever.
But some things work just for the author. "Reviewing pull requests as quickly as possible (<<1h)" would simply destroy my focus during the day.
Anyway I believe such posts are a good thing to read from time to time
