You can also have a discoverable OPML with many interesting feeds in it. I'm not aware of any clients that can find it but I think it useful enough for someone to one day implement it. Seeing just one feed appear in your aggregator just for the page you are looking at right now (while very useful later on) isn't as exciting as 10 or 100 new sub worthy subjects.
