I think the best way I can describe my reaction is by describing the effect reading novels (not blog posts or stuff on the internet, but actual literature) affects my inner mental dialogue. It affects the way I communicate information with myself. That's huge, in my mind. I speak more concisely, using a more elaborate diction than I otherwise would.
I don't want to imagine what my monologue would sound like after twitter. That's why I feel its sad.
