I found an interesting article about turning your GMail into a nerve center, and it seems to have some relevance to my work email as well.
I've long been a fan of www.rssfwd.com as a way to have blogs and sites I don't visit often, show up in my inbox. But it also looks like Yahoo! is also offering an 'Alert!" service that is in beta that does relatively the same thing, in addition to doing email notification for other things like weather, stocks etc.
The Yahoo site is: http://beta.alerts.yahoo.com/main.php?
