I do see that it can be used to easily create Internet Scavenger Hunts and Webquests. It lets you create a "molecule" filled with "atoms" (the call each topic a molecule and atoms the different parts of the collection). You can insert a website and notes into each molecule, which will also show a screenshot or even a video. The task for each can also be described. And it's easy to move the "molecules" around. And, then, best of all, you can embed your whole "molecule" wherever you want, including on a class blog or website.
