My experience with wikispaces is positive. there are lot of advantages:
-Students develop technological skills.
-Safety and encouragement to acquire a new role outside the physical classroom.
-It´s a good tool to motivate your students.
-Working in groups it´s good to get people together.
-Is a way to give big amount of material to your students.
-Increase the responsibility of your students because their actions are publics.
On the other hand, a few disadvantages:
-Bandwidth.
-The student if only depends on education through the web can feel lonely.
-Unit-technology could be a high cost and a system crash can supose a "cost" more.
