title: Converting an Array of Arrays into an Array of Strings
body: <p>I currently have an array of arrays. There are 10 single-item arrays in my overall array</p>
  
  <p>[["http://instagr.am/r/123"],["http://instagr.am/r/456"]....]</p>
  
  <p>My goal is to clean this up so that it is an array of <em>strings</em>. </p>
  
  <p>Ex:</p>
  
  <p>[http://instagr.am/r/123, <a href="http://instagr.am/r/456">http://instagr.am/r/456</a>, ... ]</p>
  
  <p>I have been racking Google trying to find a solution for this but I seem to be unable to find one and I was hoping that you kind folks could help out an emerging Rubyist.</p>
