MynoteIT

www.mynoteit.com is a website where students and teachers can compose and share notes or audio clips with other students/teachers.  The nice thing about this website is that it allows the poster to create tags on the notes.  These tags make it easy for anyone viewing the notes to quickly search on them.  Like del.ico.us you can join create bookmarks and share them with fellow students.  You can also post questions to other classmates in an online forum when you have a question.  This website allows students to keep track of assignments and create a to-do-list to make sure the work gets done.  Students can also track their grades online so they know how they are doing throughout the entire course.  An added benefit for those with mobile phones is the ability to post notes using a mobile web interface.  Best of all this is freely available for teachers and students.  I can see how this could be useful, especially for those students challenged with keeping good notes.  Teachers could also post their powerpoint slides to this websites so students could review outside the classroom.
