Web 2.0 Backpack: Web Apps for Students

It looks like it is already time to start thinking about going back to school.  Here is a nice list of student applications using web 2.0 technologies.

Web 2.0 Backpack

There are quite a few on the list I have not heard of.  Nine of them are mind mapping applications and wikimindmap isn’t on the list.

For some reason, Google is included but not Google Scholar.  Anyone else using a web 2.0 application with students?  I use Scuttle for class work, but point student to del.icio.us for personal use.
