Apple Thoughts: iPad Ready Websites Posted at Apple

"Apple added a new page to its Web site on Thursday highlighting companies that have Web sites offering content in iPad-compatible formats. The list shows off sites that are offering video content in HTML5 format instead of Flash, and includes CNN, Reuters, the New York Times, Time, Vimeo, Flickr, and more."

The webpage lists the sites that are compatible with your iPad and also has a form you can fill out to submit websites for addition to the list, as well as a help page so you can make your site iPad compatible.
