Via Weblogs in Higher Ed comes this terrific tutorial on using Bloglines: betterdays » Blog Archive » Using Bloglines (or How to keep up with dozens of blogs everyday)
This includes many screenshots, and covers how to set up a Bloglines account, how to subscribe to feeds by pasting in the RSS/Atom feed, by pasting in the site URL, subscribing to blogspot/xanga/livejournal blogs, how to subscribe to feedster RSS feeds, Flickr feeds, news sites or pretty much anything that has an RSS feed. Quick subscription via Bloglines bookmarklets are also demonstrated.
I’ve tried explaing Bloglines and RSS to people before. Right now, I think this guide is the best place to send people first.
