I Love Ruby Because ..
...of the the way it beautifully integrates blocks (lambdas) directly into functions.
Due to rich set of libraries and Metaprogramming ...
It is a hammer which can shape-shift into a nail or a bulldozer.
it isn't as gafferesk as perl
sexy syntax, easy to read and understand
Easy syntax to learn, active developer community building things that they love .
it really make you feel that programming is enjoyable..!!!
It's sexy :P
I can write code, get feedback quickly, and iterate very quickly to a working solution. Iterators and blocks working together make it really easy to put a lot of functionality into a few lines.
it 'thinks' the way I think
it's so intuitive to write code in Ruby.
Just a few weeks after I started developing my first Ruby application I feel more at home with it than with other languages I've programmed in for many years.
