This seems to be similar to Evernote, but might have more social linking capability. The idea of keeping your notes and writing 'in the cloud' can appeal to anyone who as left their materials at home. Is it right for you or your classes? That depends on just how web friendly you (or your audience) really is. ~ Dennis
This is another great tool for collecting web research and links to resources. Great for developing those digital study skills.
