In reply to Ali.

That was my point in the article. WordPress' low barrier to entry helped it gain popularity. Even on the theme development side of things, that barrier only required some rudimentary HTML, CSS, and copy/paste skills. That meant a whole lot of the users who did not know how to code eventually found a path toward becoming a developer.

In the past decade, it's become tougher to get into something that was once as simple as building a basic theme. But, the upcoming block-based theme system can be our chance to recapture some of that simplicity if we do not venture too far away from the basics.
