Whether the lessons presented in that video are examples of collaboration or cooperation, they definitely are inspiring for groups of people working together. I can hardly wait to watch it again.
The blogger's time management is instrumental when we want to talk other teachers into the conversation. The first perception people have about publishing your thoughts is the amount of time it all must take. So true. I cannot say my blogging (by which I mean, reading, updating, tagging, commenting, analysing and synthesizing in posts) is an activity that can be done in, say, one hour a day. And there is family and health to take care of. And jobs. And why not a totally unrelated hobby (like dancing tango) that can make us feel good about being playful.
