Have a look at the Notifo field in your profile. Then do something like:

https://encrypted.google.com/search?hl=en&q=site%3Anews....

You will received notifications of replies -- to your comments, at least; I presume also to posts/threads that you start.

EDIT: I should add that there is an email notification option (as opposed to IM, SMS, or whatever). You may have to look a bit on the Notifo site to find it, IIRC.
