I use Newsgator integrated with Outlook 2007 to read my newsfeeds. This works well for the 70 or so feeds I monitor. When I used it with the only feed I could find for serverfault I found that it kept on pulling down new responses to weeks or months old issues and inserting them into outlook at the appropriate date - where they languished unseen and unwanted.
I had to switch it off due to the over the top number of messages I was receiving. I found was spending too much time deleting questions relating to systems I did not have much experience in.
I'd like to suggest a more sophisticated RSS feed where you can choose things such as - Only pull X responses - Only unanswered questions - Which tags to ignore or include - Choose to see answers and/or responses - Separate options for threads I have posed or participated in
A simple page (ha ha, aren't they all simple until you have to write them) which allowed the user to select various options to enable or disable could construct a feed url. This url could use the above options as parameters, allowing more people to watch for interesting questions and to jump in and answer them.
