80% Traffic, Hit Only 20% of Website Features

Couple of months earlier, I worked on a web project. We implemented a lot of features, specifically in admin area. But after launch, what I see is, only 20% of the features are being used by 80% of the users. It convinced me, we must make and release small features as fast as possible and plan the roadmap with market feedback.

It remind me, Pareto Principle, which stats that "roughly 80% of the effects come from 20% of the causes" ...  for example, 20% of the software functions are used 80% of the time i.e. 80% users used only 20% of a software (just analyse you usage of MS Word, for example)

And, If there is 100 lines of code snippet facing performance bottlenecks. There are only about 20 lines that need optimization. Even Microsoft noted, when they removed 20% of the most reported bugs, 80% crashes were removed. Its so beautiful and great lesson for me. I can visualize it very deeply.
