Google Alerts is a service that fires off an email with automated searches of Google news or new websites daily.
Bloglines has a feature where you can make an email address under your profile and any email that is received will be "blogged" and appear as any other feed ... sort of like an automated email->RSS generator.
Add them up, and you've got a really cool way of keeping up to date with things you're interested in. You'll probably end up finding articles you might otherwise never have found, amazing your friends and workmates.
The only problem is that you will need to keep your email subscriptions private in Bloglines, since you have to receive the confirmation email which has details on how to cancel the web alerts (and so does each email, for that matter).
