Take a look at the following comment sections of WordPress blogs:
Do you see what’s missing?
Here are another four examples:
Do you see what these four comment sections contain that the first four lack? The answer lies in an optional check box a person writing a comment can tick to receive follow-up comments by email.
If I have a choice adding a comment on a blog with the box and a blog without it, I choose the box because I want to know if someone replies to my comment. Without the plugin installed, I may still comment but will never know if I get a response.
Think about that the next time you write a blog post.
You can download the Subscribe to Comments plugin here. I can’t think of a more essential plugin you should have.
