Value of Wiki and GoogleDocs

I have been rather negative recently about some of these tools, but in all honesty I am so happy to have learned about Wikis and GoogleDocs. Both of these tools are incredibly valuable to the teaching profession as they help us to be more efficient. I hear it said all the time that as a musician one of the utmost personal goals should be to become more efficient, as almost everybody is going to want you to do something. The same is true of an educator. How do you balance doing so many things at once? Partly I'm sure it's due to some sort of neurosis, but I am happy that the other half is in strategizing your work. These tools help tremendously.
