RSS, How do you get on your page?

Hello,
I really want to place some RSS on my blog and my webpage. I know I need to get an aggregator (spelling?) and I know that Yahoo offers a feed I would like to use. They are also my website host, so that may make it easier.

My question…

I have been looking at examples of RSS and it’s confusing me. I wanted the RSS to show up in a news ticker of sorts. Is that possible? Just like a small window inside my page. Most examples I have looked at have been “desktop based”. I can’t tell what is made for web sites and what is made personal viewing?

Any help or clarification would be very much appreciated.

Thankk you
