1. You fill in a form with the URL of an RSS feed
2. You use the form to make choices about how you want the html on your page to look.
3. The form generates a bit of javascript code that you paste on your web page

The JavaScript code can be as much as 800 characters long, but you do not have to read it or understand it. You just copy it and paste it onto a web page. When anyone loads the page you created, the JavaScript fetches the RSS, reformats the RSS into HTML, and displays it on your web page.

You may find that these services differ in more than appearance. Some evidently cache requests and do not update as fast as others. Some may be more reliable and some go offline or be non-responsive more often.

The examples at the left all use the URL http://del.icio.us/tag/govdocs2 but each uses a different service.
