Gibbon lets you easily create what they call “flows,” which are basically lists of web resources with instructions written by the flow’s creator.

I think Gibbon has ambitious plans but, for teachers, it’s an easy tool for teachers to create Internet scavenger hunts for students and for students to create them for their classmates.

I’m adding it to The Best Places To Create (And Find) Internet Scavenger Hunts & Webquests.
