FeedBot.link - If You are visiting your favorite site and can't find the link to the RSS news feed on the page, clicking the FeedBot.link bookmarklet will scour the page, put a FeedBot icon next to any likely news feeds, and modify the link to display on the FeedBot viewer page when clicked.
FeedBot.find - If After clicking the FeedBot.link Bookmarklet, a link to your favorite site's news feed wasn't found on the page. FeedBot.find queries Feedster and displays any likely RSS/XML news feeds it finds. (click FeedBot.link to view the found feeds)
