Readers can comment on my blog, but the comment won’t appear to the public. When someone comments, I am notified it by the server and I try to respond to everyone. I think if I open up the comments section, it might become a discussion forum, there will be an additional responsibility for me. So, zero-comments policy as opposed to no-comments policy.
I really like it if someone comments. It is the desire to interact which has led me to blog. So please comment if you want to say something. I will try to respond and we can discuss as much as possible.
