title: Where is Erlang used and why?
body: <p>I would like to know a list of the most common application/websites/solutions where Erlang is used, <strong>successfully or not</strong>.</p>
  
  <p>Explaining why it is used into a specific solution instead of others programming languages would be very much appreciated, too.</p>
  
  <p>Listing BAD Erlang case studies (cases in which Erlang is misused) it would be interesting, as well.</p>
