The best way to keep up to date with your favorite sites and blogs is by monitoring their RSS or Atom feeds with a News Aggregator. As far as application-based news aggregators go, my favorite is RSSOwl. But, if having a separate application isn’t your cup of tea, then you’ll probably be delighted to know that Safari, Firefox, and Thunderbird can double as news aggregators. Of course, if you read your feeds in more than one location (for example, at home and at work), then you may want to use a web-based news aggregator. Currently, my favorite web-based news aggregators are Bloglines and NewsGator.
