RSS & Newsreaders

I have subscribed to State Library Victoria Read Alert RSS feed and the ABC Science RSS feed today. There is so much to read I dare not subscribe to anything else.
Watched the Feed Me - a gentle introduction to internet feeds - from Palinet. It tells me that Bloglines is at www.bloglines.com/ and is web-based whereas some feedreaders are from a client program installed on my computer. Feeds are headlines with a summary and an option to read more... Also CompleteRSS is a feed directory. Otherwise an orange box with RSS, XML or ATOM on webpages will connect the feed to my feedreader.
