title: What are some real use cases for going with a NoSQL Document Store db?
body: <p>I have been reading documentation and watching screencasts specific to Mongo DB over the past few days and I am at a loss for when a solution like this would be better than a typical pg or mysql environment. </p>
  
  <p>Specifically, my question is under what circumstance (w/ use case would be nice) would you want to go the nosql route?</p>
  
  <p>Thanks!</p>
