iGoogle.  IMHO, one of the simplest and easiest-to-set-up aggregators available.

Basically, you either sign in to your Google account, or create one, and you can set up little “widgets,” or boxes on your page, which hold things you use frequently, such as a calendar, weather forecast, news feed, your various emails (yes, Google can import ALL of your email accounts into one place- no more checking 5 different sites to read your email), links to your favorite websites, and so much more!
