All of us use some kind of software, no matter are you a programmer, designer, architect or a journalist - you need to have tools to make your work done.
What I noticed, many people unfortunately don't spent any single minute to learn more about software they use. Maybe they don't want to? I believe, it's not about lack of good will. They just don't know how rich functionalities todays softwares provides and how big impact on their productivity those unknown functionalities could have.
And believe me or not, if you will sum up whole time which would be saved, because of using them, there would be lot of it.
