However, I was reading the Occam's Razor blog of Avanash Kaushik, and he made an interesting point. A blog should be written more like a book than a diary. No one wants to read journal about work, but book written in installments would be worth reading.
After fourteen years of teaching, I have some definite thoughts about the education system and why it needs to change. My time would be much better spent writing about how school could be much more effective, especially if online video sites like mine are part of that.
