I'm a Rubyist with a lot of admiration for Python. Both languages are
similar (in the grand scheme of things) and each has huge pros and cons.

Python does not click for me in the same way as Ruby does not
click for perhaps the majority of programmer-kind. German doesn't click
for me either and 100m+ people speak that ;-) But I recently saw an
example of WHY Python taxes my Ruby brain a little.

I found some code at http://lukeplant.me.uk/blog/posts/why-learning-haskell-python-makes-you-a-worse-programmer/:

// How to use this:
// 1. Go to the desired profile page on coderwall, like http://coderwall.com/marcinbunsch
// 2. Paste this gist in the JS console 
//
// You can also probably use this in greasemonkey and dot.js
//
// Also, it was tested in Chrome, Firefox and Safari, it probably will 
// not work in IE, but I just don't care about it ;)
//
// UPDATE: Coderwall made changes to the site and I cannot retrieve the achievements, so they are hardcoded, taken from a cached version of the achievements page
