Rss Readers
Here is a directory of RSS readers, which are used to scan or read many sites at once. They are part of RssSyndication; you use them to read RssFeeds, either just the headlines, or the headlines and a short description (or even the whole text) of each item. You can click on any item to see it in it's regular web page context. Some readers use a web interface, some are a desktop program, separate from your web browser. Some readers let you easily post what you're reading to your own weblog (AutoBlogging).
There are dozens of lists like this. But I like that this one is a Wiki and also like the way it's organized.
