I think a lot of startups (and companies in general) become so enamored with their work that they lose sight of the real value of what they're doing. For example, as the author said, losing the forest for the trees: getting tunnel vision on one very good feature causes stagnation to the rest of the system as a whole. It doesn't move forward, it just makes one 10/10 feature in a 7/10 system. Metrics that show how useful a userbase finds one feature are always good because they keep the programmer's eye on the difference between being objectively useful and just being neurotic.
