Blog vs Blackboard

We have had many conversations in class about blogging vs using Blackboard. Through conversations with others in class I feel that comfort level is the most important factor when discussing preference. It is taking me some time to become comfortable with blogging.  I find it difficult to navigate and think  some of my blogs have been lost in outerspace . I like Blackboard because there is structure. The teacher provides one or two threads and  the class  begins a discussion. I feel connected with everyone in class. With blogging I feel that we don't really read everyone's blogs, let alone comment on it. I would love to use Blackboard with my classes, I would feel my students were safe and think it could become a great teaching tool in the future.
