I was wondering what other educators were planning for Blog Action Day 2008? This year's topic is Poverty. Those who participated last year will remember the topic was Environment. It is a great opportunity to produce project based artifacts.
Thanks for the great question. it seems to me that if you want to keep your Ning private, you would not want to share your url.
Yes, that would be a concern, but I think you could overcome it for this project. If you have a wiki, you could put all student's posts for Blog Action Day on your one wiki page with only first names, made-up names or just numbers. I recommend wikispaces because they are giving away 100,000 free private education account.
