From the site
Trailfire enables you to discover the web through the expertise of others. Follow a trail and find what you need. Or share your own expertise by making a trail of web pages.
Making trails is easy. Place a ‘trail mark’ (like a ‘post-it’ note) on a page with your comments. A trail mark can contain text, images, videos and other media types. When you give several marks the same ‘trail name’ you are forming your own navigation path on the web. We call this a ‘Trail’. Trails can be private or public. Trails can be shared via email, by posting them on any website, or by publishing them on Trailfire.com.
