What does the “Web devs are not programmers” gang think of people like Mark Zuckerberg?

I don’t think any such gang ever existed. A web developer is a software engineer who only builds web applications. But, every web developer who is employable is a software engineer.

Secondly, Mr. Mark Zuckerberg, in my opinion, is more of a business owner than a hardcode programmer. He has proved through his unique business ideas for Facebook that people of any race, ethnicity or origin can meet online and when they do something beautiful can come of it. 

Mr. Zuckerberg is a marketing genius, but he never invented anything. He will be remembered for his path breaking ideas, but not as a seasoned programmer.
