Yes. The Twitter API and the search functions included have opened up Twitter to so many analyzing tools. Twitter itself looks constantly for "trending topics", i.e. what is being talked about most on Twitter at any given time. Other services use methods to do the same thing.
A fun example is http://cursebird.com, which does real-time tracking of swear words on Twitter. Of course, you can easily track any such words, or topics, or information you needed in the same way.
