I’ve used FeedDemon (for Windoze) as my RSS aggregator for several years now. I see that it’s now being offered for free, which is a very good deal indeed, since it is one of the only pieces of software on my computer that I was happy to pay for. FeedDemon syncs with a web based rss aggregator, so you can use FeedDemon on your computer at home and then while away the day at work reading from the web based rss aggregator. (I never use this feature, so I’m not recommending this in particular.)
Here’s an account of RSS in case you’re unfamiliar with the concept. (The last few semesters that I’ve taught, I’ve asked students if they knew about RSS feeds, and very few did.) If you’re familiar with the concept, but not convinced it’s an improvement over just clicking on bookmarks, you should really try it.
