My Yahoo/ RSS Reader
I vaguely remember reading about this in beta test mode. Haven't tested it yet but sounds very promising for getting people into feeds. I've mentioned using an aggregator to a couple of people to read our library feed and they glaze over. But they might get it if its a part of Yahoo, for better or worse.

10/7 Update: I tried out the My Yahoo RSS service and it is really easy to use. I added the Decatur Library news blog by copying and pasting the feed. That's supposed to make it searchable in their RSS database but it doesn't show up yet. I added an "Add to My Yahoo" button too, which was very easy. I also realized there's no feed for this blog so I'll fix that next week.
