#2 Create a blog: Practicing what I preach teach!

Year 10 students in a class I am teaching are currently blogging their way through their programming project. Now it's my turn! I have reservations with disclosing my thoughts to all and sundry - I am sure others of my generation also have these reservations - is this because of a lack of confidence (what are my thoughts worth?), old-fashioned (but useful) social inhibition or wanting to retain control of who these thoughts are shared with and when?
