This hidden gem from Stanford University doe not give the pretty effects of Wordle, but does give several awesome features that allow students to really analyze a word cloud. One unique feature allows words to be listed by how common or rare they are. Also allows for words to be listed in alphabetical order. Wordsift allows the user to click on words to view in an online visual thesaurus with dictionary, google images, and word sentence placement. It even allows the user to view words by subject area and cross curricular areas by unique color coding and definitions that relate to specific disciplines.
