I am a user. And not a week goes by without my mind being blown by a simple fact that most of us appear to have become blind to.
The Internet is free!
I owe my career to the web being a free resource. I think you might too. The importance of the web's underlying infrastructure being available to everyone cannot be overstated. The web was built with the efforts of those who learned from the web.
So even though platforms make life easy, there must never come a time when they become the default standard for web publishing. There must always be open standards, open protocols, open methods of doing web things that anyone can learn and build on top of.
