Feeding Frenzy

Aggregators can live in two places: on your desktop or on the Web. There are some free desktop aggregators out there, but you'll probably have to pay a fee to get a more robust model. The list below is not exhaustive by any stretch of the imagination.

Windows Desktop Aggregators

Mac Desktop Aggregators

Web-based Aggregators

The services listed below are free. I recommend these as a good starting point if you're not sure what you're doing.

You may also see buttons like these when you're surfing the Web:

Add to My Yahoo
Subscribe with Bloglines
RSS Feedster

Rather than linking directly to a feed, such buttons enable a one-click way to subscribe to a feed via a Web-based aggregator service.
