Comments on Blogs

I took a lot of time off from this blog and now I am back, trying to read and catch up on the many blogs I read. I came across a post in Blog of Proximal Development on Cliques and Comments. Here I find myself doing exactly what he described his students doing. Rather than writing comments within a blog, they often commented on other students' blogs within their own blog. Personally, I find it easier to do this. Why? It is less public - only people reading my blog will see what I am thinking. I have a sense that a smaller audience will see what I write and I feel more comfortable playing with my thoughts in a less public way. Is it insecurity? Is it that I want to draw people in to me? I'm not sure, but it just seems more comfortable.
