Ruby Symbols vs Strings in Hashes

Question

I have this hash:

{
  \"title\"=>\"Navy to place breath-test machines on all its ships\", 
  \"url\"=>\"http://feeds.washingtonpost.com/click.phdo?i=a6         


        

Answer 1

Why?---Because :url and 'url' are different, i.e., :url != 'url'.

Shouldn't it work with either?---No.
