See, most (if not all) bloggers love receiving comments. It helps us confirm that someone is out there reading what they've taken the time to read. It validates us, and we all need some validation.
Don't know how to leave a comment? On most blogs, all you have to do is click on the "comments" at the end of the post. I've made an example and put it in the yellow box:
If there aren't any comments, click on "No Comments" A few blogs have theirs at the beginning of the post, just after the date of the post. Once you click, you'll see a box where you can write your comment:
After you click "Publish", some bloggers prefer that you verify that you are an actual person. With some comments, you may be required to put in your name, as well as other information. Don't let that scare you; the blogger is protecting herself/himself from spam, as well as having a way to contact you to respond to your comment.
There are different formats for the comment section, but it really is that easy. Don't feel like you're "stalking" the blogger; commenting is one way we all get to know each other! Don't agree with what was written? It's okay to state your opinion...that's one way to open up a discussion.
If you're reading this post, don't be shy...I love comments!
