What exactly is RSS?

...and how do you use it

[kodaks]

I am new to RSS and am wondering what exactly it is.

I was looking on the YAHOO! RSS News page, and it looks as if you can put YAHOO's headlines on your website. I am wondering if this is true, and if so how do I do this? Thanks!

RSS is an XML-based syndication format.

You might want to try the RSS and Related Technologies [webmasterworld.com] forum for more information: there are some excellent explanatory threads in there.

Thanks, I will.
