Here is the image of the three of them in the diagram, but this is the way I have been thinking about them:
- Google+ Community = Conversation (This is the daily flow of conversation that leads to better information sharing and gathering)
- Google Drive = Collaboration (These are the working documents and ideas that require the most work and attention. These are not static, but rather are always in "draft")
- Google Sites = Communication (This is how we communicate decisions and track progress. We are setting clear communication guidelines and working agreements here.)
I hope this all makes sense.
