Just finished a presentation on this new tool Trailfire. What a great way to lead your students through a presentation of websites; or to teach searching; or how to register for a site.
I can imagine so many uses - ready to give it a try.
from their website:
A trail is a collection of web pages, assembled and annotated by any Trailfire member, on just about anything under the sun.
The basic concepts are simple
» "Marks" with the author's comments are placed on any web page.
» Trails are created when multiple marks are given the same name.
» This links the pages together, creating a sequential path for navigating the trail
All over the web, as a Trailfire member, you'll see this Trailfire icon marking a trail. Mouse over the icon to open the mark and enter the trail.
