After speaking to Chinmay about the default value, we decided to accept this pull request, with the default value for informed.on be 'false'.  Inside LinkedIn, we will pass in a value via a voldemort build&push job property, defaulting to 'true'.

Before I pull in this request, could you please make the following minor changes:
1. Please define two constants here, one for the informed.on string and one for the default value.  
2. Also, if you don't mind, please change the constant 'informedURL' into a proper constant name, like 'INFORMED_URL'
