Marco Polo is merchant who wrote about the ancient silk road. Before many of them traveled through that, but he only wrote it down. Chris who found the css-tricks is similar to him, he wrote about css and eventually build a business from it.
Those Who Teach
Think through the people who are well known in your industry. Why do you know who they are?
Are they the most talented? Sometimes, but often not.
Almost always it is because they teach.
To be known, you must teach
The way I see it, you have two options: keep your skills and knowledge to yourself and be quickly forgotten (like the first explorers) or take the Marco Polo/Chris Coyier path and share what you’ve learned so that you will be remembered.
