What is Google Reader and why should you use it?

Google Reader is a free, Web-based reader for RSS feeds. You can find feeds on nearly every Web site. RSS feeds offer a simplified view of Web content down to just text, pictures and videos--minus the site's style and formatting, which can sometimes hinder or befuddle casual reading.

Google reader lets you subscribe to these feeds as easily as typing them into your browser's address bar, and lets you read them like you're browsing through e-mail. There are many online RSS readers available, but Google is one of the best. It's easy to get a grip on Google Reader basics, but there are several tips and tricks that can make it extremely productive.
