I realized that I wasn’t clear in this short post I wrote awhile back.
I have absolutely no objection to authors commenting on my blog. I was only thinking of author comments on reviews of their own books. I have gotten some very sweet comments, but as I said, they stop discussion (of the review or the book) dead.
Anything else is fair game. I enjoy chatting with many authors because they’re passionate about the genre and have a lot of knowledge about it that’s different from mine. Also, MST3K jokes.
