The technical definition follows - RSS is a family of Web feed formats used to publish frequently updated works—such as blog entries, news headlines, audio, and video—in a standardized format. RSS feeds can be read using software called an "RSS reader"
So what does that mean? RSS feeds simply deliver your content directly to you without you having to go and find it - anywhere you see the little orange logo - you can click on it and get an automatic feed of that particular content type or subject. RSS Feeds will deliver the "chat" right to you, and they work across the entire bizchat site. We like Google Reader - to find out and sign up (it's free!) just go here.
