Selecting a 'Family' of Programming Languages

Hey /g/,
So as someone who just recently got into programming I've been doing a lot of research into what languages are best to know or best to learn form. The resources I've found that come off as the most authentic (as if I know) suggest learning a variety of different languages that cover distinct types of programming that help maximize one's flexibility.

In Reymond's popular "How to Become a Hacker" page he writes:

"...I think it is probably best to learn C and Lisp first, then Java.

...

[It would be best to learn] Python, C/C++, Java, Perl, and LISP. Besides being the most important hacking languages, they represent very different approaches to programming, and each will educate you in valuable ways."

And in the suggested "Teach Yourself Programming in 10 Years" reading seasoned Google hacker Peter Norvig suggests:

"Learn at least a half dozen programming languages. Include one language that emphasizes class abstractions (like Java or C++), one that emphasizes functional abstraction (like Lisp or ML or Haskell), one that supports syntactic abstraction (like Lisp), one that supports declarative specifications (like Prolog or C++ templates), and one that emphasizes parallelism (like Clojure or Go)."

What are /g/'s thoughts on all of this? Any sharp disagreements or agreements with what either person said? Personally I've never heard of Clojure, Go, or ML before in my life. How do web design languages like HTML or PHP fit into all of this?
