Language advocacy

• Lisp: author makes a successful effort to show Lisp's virtues to the non-initiated. This tends to be a not so easy task, since the sources of Lisp's superiority are the very same things that make it look so alien to programmers versant in ALGOL descendant languages.
  
• Scheme: Great language, naive writing. Scheme deserves better.
  
• Smalltalk: This article highlights very well a lot of the points that struck me personally when I first came into contact with Smalltalk.
  
• More smalltalk: "Smalltalk: Requiem or Resurgence?" I'm not very optimistic... But, who knows?
• More lisp: When you get bored with reading about computer programming languages, you can relax, sit back, and enjoy this video about computer programming languages.
