I like your article about the topic, because every application developer should think about how to handle logging and error handling. I would recommend you take a look at error tracking services for production use, because:
* It will group the errors to similar error groups, so you won't get notified about the same error multiple times
* You see how often and at what time the errors occurred
* You get notifications to your Hipchat or Campfire account
* Error reporting of background jobs
Maybe you want to try out https://exceptiontrap.com and send me your feedback (I'm the founder, but there are other services too).
