If Visual Basic was the language with the most number of beginners and programmers, and I had the best answers to Visual Basic questions, I could be Chuck Norris instead.
But I don't find Visual Basic challenging or interesting. Neither C# or Java for that matter.
I'm good enough to make a living, and good enough to help people on SO. One of the nice things about programming is that what you find interesting, I might not and vice versa - hopefully there will always be enough people who find a variety of topics interesting to hope those who have problems in those topics. But yes, considering rep as a proxy metric for programming awesomeness would be a mistake IMO.
But there are numerous unsung heroes who, for whatever reason, do not get the recognition they deserve.
Like those on Stack Overflow who are investing the same amount of time and effort as some of the top rep contributors, but in areas that are not as reputationally rewarding.
But there is also a large group that are not posting on Stack Overflow, who are more likely to be working somewhere across the thousands of forums, git repos and mailing lists that developers inhabit. Out of the limelight, and with no reputation points to show for it.
Clear, concise, correct, robust, efficient.
The strengths and weaknesses of various languages boils down to how easy or hard it is to meet those factors + how good the tooling, library ecosystem and learning resources are.
Meeting those five factors with a language like Visual Basic is harder than a language such as Python or F#. Coders who write good code in VB deserve respect.
Your view on 'challenging' is too limited. If a language is easy to pick up but hard to master is it challenging or not? The goal should be good code, regardless of the language.
That's neither here nor there. He does, and he got to be Chuck Norris.
Besides, who could have been the Chuck Norris of Haskell or Idris or whatever rocks your boat. Have you answered the most questions in your preferred language?
