pros

Lets say what we like about programming languages for a change.

C: Very fast and simple syntax.
C++: Has some useful standard libraries that C doesn't have, like vector and map.
Java: Has a very good garbage collector.
Lisp: You can make intersting self-modifying programs with macros.
PHP: Is one of the more readable scripting languages
Python: The forced indentation of code is an interesting idea
Ruby: no comment

Ruby: Slightly less disgusting anonymous function syntax than Javascript
