Artisanal Framework Design

There is no a thing as code-pollution since every program written express the genius of someone in at least some particular area which can be useful for anyone. NIH Syndrom is not a shame, it's not shame to reinvent the wheel, it is the way of learning, it is the way of rethinking problems and providing new solutions which at least solve the problem for the one who created it. No footballers learn football/soccer only by watching other programs kicking the ball.

Writing software is never a shame. Some softwares are successful but one should dive the ins and outs to understand their success. Some have historical power like Windows or in the hardware space QWERTY keyboard, or marketing power like Apple and Intel. Another comparison would be to compare software to languages not computer languages, Latin was codified by some people, English by the people, and I think everybody will agree that English is easier to learn and speak than Latin. Todays softwares are Latin. While still remaining as useful and as powerful.
