It is too easy to miss a story posting or have your RL disrupt blogging time.

Well...okay. But the only place I'd be likely to let a person know is in the story post itself. So if you miss that, you'd miss the shout-out, too, wouldn't you?

Besides, it's not letting a writer down to fail to read or comment. It might be in a fic-exchange type of scenario, if someone's written a story specifically for you, but not the vague kind of thing I'm talking about.
