Of course, you are welcome to add comments and replies on any of the blog posts as well. Sometimes it’s good just to write down your thoughts as they strike you. It doesn’t have to be hugely profound, and the questions can be as complex or simple as you like.
You can view all the latest comments that have come in by clicking on the comments feed at the top right of the blog page. And if you use feedreaders such as google reader you can subscribe to it, too.
You’ll notice that posts on the homepage say “leave a comment” if there are no comments yet. And if there are comments, it will tell you how many. Clicking that link will take you to the comments section that appears below the post. Is that fairly clear? 🙂
