All websites should provide RSS feeds. It's clearly the NextBigThing for the web, the first emergence of usable, useful agents on the Net that pull content for you. Unfortunately, it's mainly only blogs that provide feeds, but I've found a couple of wonderful resources to get around this. First off is Syndic8, an enormous list of feeds. However, if you the site you want to subscribe to isn't listed there, just create your own feed with MyRSS, a free screen-scraping service. Down with the tyranny of HTML!
