It seems like the only way to get notified of certain events is to poll the site continuously. And as per the current policy, it seems like there should be at least a 2 minute delay between requests.

So therefore, I am proposing a notification system whereby an app can 'register' for certain events and receive a notification when they occur.


  • an app calls /0.8/notify/questions?intitle=silverlight
  • the app provides a URL
  • whenever a new question with 'silverlight' in the title is posted, the URL specified above is called

    This is what pubsubhubbub is for. I imagine the answer will be no because of complexity. I would rather just have a firehose with every change in it.

Its far too late in the v1 game to add something this complex.

Note that the current policy is that you shouldn't be polling faster than once a minute, not two minutes.

    @George - We're not going to commit to ever implementing such a feature. Not to say that it is for-sure never gonna happen just that its too early to [status-deferred] this. Jun 11, 2010 at 0:12
