neologisms: clouds and word clouds

One of the hot new words in online computing is "cloud," suggesting that our data is stored somewhere up there in the heavens, in a pretty, fluffy cloud. There ARE "virtual (i.e. not real) servers," that sell and organize data space, but, ultimately our information is stored in a physical server sitting somewhere firmly on earth -- possibly in a foreign country.

"Word cloud" is a nifty graphic device that analyses the number of times various words are used in a speech or a piece of text. I see them in the New York Times Magazine and on CNN most often. Often, it's sort of cloud-shaped. The more a word is used, the larger it is in the word cloud. Sometimes the words are shown in different colors. For example, one could create a word cloud of the State of the Union Speech, showing how many times "God" or "America" or "terrorism" or "jobs" is used. Computer programs exist to create these. If one did a word cloud of Scheub's book, Story, for example, one might find the words "trope" and "image" and "palimpsest" looming large in the cloud. If one created a word cloud of student reviews of Scheub's book, on the other hand, perhaps the larger words would be "dry," "dense" and "unintelligible." Heh, heh, heh. (Etymology, Middle English, hill, cloud, from Old English, clud, mass of rock or earth, possibly related to clod.) (So, a cloud is sort of a clod in the sky?)
