You are mistaken. Provided you have appropriate support from your language or its libraries, accomplishing this is trivial. Using Perl and Regexp::Assemble, FishTwits is currently tracking 1,358 words/ phrases and, for each tweet, building a list of which words/phrases appear in that tweet. It's very doable (quick, even), despite having far more than 10 keywords involved. -- Dave Sherohman
