title: How to publish a persolized newsfeed on users stream in Facebook?
body: <p>I read the Facebook developers guide, but I'm not sure to have well understood wheter my goal is achievable or not.
  I have developed a small app that asks to users their topics of interest, so they will receive filtered updates on those topics. This currently works, my database stores users and topics. 
  Now I want to publish on registered users stream a newsfeed if there are updates on the topics they selected (in the oauth dialog I asked permissions for "publish_actions"). 
  My app doesn't use OpenGraph, I would that the newsfeed has my apps as title, a small picture and a brief description and it links to and external site (not mine). 
  The feed is personalized, so that's why I don't use a Facebook page.</p>
  
  <p>Is it possible to realize this?
  Thanks in advance </p>
