Right, first thing you need is an RSS Reader.
The Google one is very good and if you already have a Google account (for GMail, iGoogle or whatever) then it is minimal hassle to sign up to.
Websites publish "RSS feeds" and you can "subscribe" to them.
Typically it might be something like the news headlines.
I have 30 feeds that I subscribe to. The net result is that instead of me visiting 30 websites every day to see if they are reporting anything of interest, I can just look at my RSS Reader and see them all in one place.
