I read alot of other author's blogs. I don't often comment--sometimes because I have nothing to say but "Great post!" and others because there's no reason to comment. Such as a review. (Unless it's mine in which case I'll thank the reviewer.) But with reviews on other's works, I've read the blogger's words and either liked them (and the book) enough to put it on a To Buy list or didn't and will skip it.
But there's so much else out there! News on the publishing world, on what other authors are doing, on who signed with whom or who didn't sign with anyone to self-publish a novel.
