Should Authors Comment on Reviews?

There was a time where I believed yes – a simple "thanks for taking the time" was polite. Then, I went through a phase where I said no – seriously, I need to stay out of it. Now, I'm not sure anymore.

I'm not talking about correcting people or arguing with them if they give me a low score. I just mean thanking someone for taking the time to post a review on their blog. And my answer is – I don't know.

So, I'm putting it out to everyone to help me answer this question: should authors comment and thank reviewers who do reviews of your work on their blogs?
