Against the misuse of "porn"

The word, that is. Although I know it is useless to protest against trends in language, I still want to raise my feeble voice against the mainstreaming of the word porn in everyday usage, as a synonym for anything that is enjoyable to view. This perfectly harmless and rather enjoyable photo spread of creative bookshelves is entitled Bookshelf Porn. Why? To attract internet traffic, of course. But such usage represents a degradation of language, a smashing of detail, nuance and accuracy, in the name of maximum (and thereafter decreasing) impact. Language shapes and is shaped by culture, certainly--Normal is just a setting on the washing machine, and Sinful is just a word on the dessert menu nowadays. But what is being lost seems to be worthy of preservation. The Presbyterian writer Frederick Buechner said that "Lust is the craving for salt of a man who is dying of thirst." This dessication of spirit is reflected in the language, when porn--joyless, loveless, stage-lit, rubber-sheathed, mercenary porn--is used as a synonym for honestly rewarding delight.
