I've noticed that many people who I have sent here
[as well as various others such as: visitors who arrive here out of curiosity]
aren't too familiar with the whole blog concept.
Chiefly with the fact that one can leave comments at the bottom of entries.
By commenting, one can respond to what was said by the one who posts in the blog; also, one can leave a message [yes, it can be off topic...somewhat] for the author to read.
In this particular blog, you can access this interactive feature by clicking the orange link that has the word "comment". If no one has left a comment, the link will read no comments if someone has left a message in that section the link will have a number and then the word comment or comments.
For the latter situation, it would look something like this: 7 comments.
I hope that this helps!!
(-if it did, you should know where to go and what to do- yes, leave me a comment! ^_^)
