Is this working properly right now? There was a problem where a new 
question with a subscribed tag did not trigger a notification, but there 
would be random ones later if one edits the original question: 
http://answers.ros.org/question/1401/email-notifications-on-interesting-questions

In general I like the "StackOverflow" format, but it's 
counter-productive if you cannot rely on the subscriptions and regularly 
have to check the site instead.

Best,
