From Marnie Webb's Blog:

It's a ridiculously easy way to read the web. So, how many bookmarks do you have in your browser? How many of them have new information? Does it make you sick to your stomach to think of clicking through all of those to discover whether or not the website owners have added new, interesting content? Via RSS, you can subscribe to many websites and very easily find out whether there is new relevant content. My bookmarks no longer scare me. In fact, I rarely use them.

It's ridiculously easy to share the information you get. One of the nice things about RSS is that information comes to you in manageable chunks: a NYTimes headline with a sentence-long article summary; a complete weblog entry; a teaser for a longer weblog entry; the pointer to a newsgroup posting; an email announcement list; events. You can push that information out to communities who may interested -- simply send it via email or put it on your own blog.
