A couple of weeks ago I read, and commented on, a personal blog written by a person whose company sends me a weekly e-mail. Much to my surprise, the next day I got an e-mail from an adversary of the blog owner telling me some "unsavory" things about him, and reasons I shouldn't associate with him. I am completely aware of, and comfortable with, this person's past; I resented the attack on him and what he stood for.
The next time I tried to read the blog, I got a screen telling me I couldn't unless I had been invited. I corresponded with the owner, received an invitation, and today I accepted an invitation to read a private blog.
I'm looking forward to reading this blog's words of wisdom, and being able to comment without being attacked myself.
