Awh, Evee! I comment whenever I read things - subscribing is the issue. I don't check my e-mail -- why bother? I just check to see who updated, but, I don't know.
In an ideal world, you would have the same number of comments for each chapter as reads. Even if they're critical, they still help. But we don't live in an ideal world. As for me, I always comment and I love getting comments myself, but I really don't understand how people can have such disrespect for the time and effort authors put in to their writing as to not give that 30 second consideration. Sorry, that last sentence was a little convoluted, but you get the idea. I'm agreeing with you ;D
