title: Is it a bad style of using key: value instead of :key => value in a hash of Ruby 1.9
body: <p>The teams I joined discourage using <code>key: value</code> even for a new project, despite it requires less keystrokes and is more alike JavaScript (I do not like PHP things).  </p>
  
  <p>Is it considered a bad style in Ruby's community? Do not think this is subjective question. I am just asking about the common trends.</p>
