Triumphs of the Worse

I know I seem like an irrelevant dinosaur to you node.js hipsters, but there are some valuable lessons floating around there that the next+1 new hotness would be wise to consider.  They all stem from the questions: what were the popular web languages?  And why?

Functional vs. Object Oriented

By the time I reached my first programming job, I had learned a number of languages well enough to program in, and thought of myself as a pretty good programmer.  Then I met Brian, who frequently talked about Lisp, but had trouble articulating the advantages himself.  (This turns out to be a common problem.)  He introduced me to the SICP videos, and I found Slava Akhmechet's "The Nature of Lisp" essay on defmacro.org at about the same time.  Certain things about Perl and Javascript suddenly made sense, filling me with newfound wonder.

What I thought I knew about OOP as taught in college—Encapsulation, Polymorphism, and Inheritance—seemed like a sham.
