I follow a few blogs, most of them on WordPress, and I go through my reader feed every morning and read the highlights of each new post, and if the teaser catches my fancy, I will read more, and even the entire thing if I like it. I would then click on the little “like” star at the bottom of the post if the poster has configured their blog to support it. And if the post warrants it, I might even leave a comment. And this is where so many bloggers lack etiquette.
If I took the time to read your blog, and actually comment on what you wrote, please have the courtesy to at least acknowledge the comment. Leaving a comment unacknowledged is tantamount to someone telling you something in person and you just look away withoutsaying anything.
We all blog to get our voices out there, but no matter what, we would love to hear what others think of our writing. If we didn't, then we would configure our blogs so that people could not like or comment on the posts. So if you are going to blog, and someone takes the time to comment on your posts, at least acknowledge them. It just common courtesy.
