Trailfire offers a new way to categorize, recommend and share websites. You build a collection of themed sites to share with the community. In order to build a trail, you must register with the site, but you can view previously built trails without registering. The trails can easily be viewed by category, most recent additions, popular, and "hot".
This is an interesting way to share sites. It may be a new way to create online pathfinders for subjects. Additionally, we have been looking for a site kind of like del.icio.us to use for our children's links. Because this allows thumbnails of screenshots, making it more accessible and welcoming for kids, this may be a good solution. Definitely something I need to keep my eye on.
