Thing 9 Online Collaboration Tools

This Thing is one I want to pursue this year as in the past Google Docs has been a challenge to get to work. Notable in this assignment, editing shared documents as a learning tool, the comments on the pages in both Google Docs and Zoho Writer are about the frustration of not being able to edit. Also notable is the enthusiastic from colleagues in their blogs about it's collaborative power. I'm a believer but would like to be a user!
