One teacher says she wants to post the lesson and have students respond to it, but she wants the students to see each others comments and interact, but it can't be too technologically advanced, because she's not comfortable with technology. Oh, and she needs to be able to delete comments that are inappropriate.
So, you want a blog?
I pipe up with the fact that I've been using Blogger for 8 years, it is free, and you can moderate comments. Why give a technophobe something big and fancy if they don't know how to use it or are afraid of it?
