My site Tagxedo (http://www.tagxedo.com) makes is a word cloud app, so naturally I set up a Twitter search on the phrase "word cloud", and I track it using Tweetdeck.
However, I think at least 1/3 of the tweets captured by this search is of the form:
"Stop using the word cloud!"
"If I hear the word 'cloud' one more time my head will explode!"
and so on.
