There is a blog post about how Wikis and other Web 2.0 tools support the online learning community. I agree with using these tools to help foster a healthy collaborative learning environment. You can read this blog by clicking the following link:
I found a blog from another educator that discusses how communication and collaborative interaction are intertwined. The blog list some of the same tools I have listed above that support the collaborative online learning process.

There is another blog on the talks about how collaborative interaction has transformed DE. I found this to be an interesting read. I do have to question the statement in the blog that there is a level of expertise found in DE that can't be found in a face to face course. I understand that DE can offer global perspectives but I have experienced face to face instruction that does the same. The college I attended had and international exchange program which allowed students from different countries to attend the university at a reasonable price. This provided a campus that had a diversity of thoughts and ideas inside the classroom.
