Technology and Freeware

Google Docs is great for collaborative brainstorming for students and teachers. When the need arises for a Vetch-class that are submitting plans to build a house or a math-class submitting group or individual related formula to a equation. The only disadvantages I see for students and teachers is the lack of physical interaction, in which case I believe every human-being needs. I guess that's what they made the web cam and iphone4 to do.
