I agree with this discomfort. I don't like leaving comments on my friends' blogs either.
Sometimes there are things you would like to say privately, that you wouldn't say in a roomful of strangers. Online, anyone can see this page.
So, I'm making a change. All comments posted to my blog will be kept PRIVATE, and not published. Only I will see them. They cannot even accidentally be published.
Feel free to type what you will in response to any of my blogs, and know only I will receive your comments.
