I only ever read over and respond to what blogs I find interesting, so to answer your question, no I don't.
I read them all. Hell, I have nothing better to do, so why not? Also, I HATE NOT BEING IN THE KNOW. I often feel like a total moron if I am clueless or the last to know something , therefore I browse the entirety of the forums for new stories and such; blogs just happen to be among the places I look.
