A cool app, but a sad statement about the state of journalism that PR fluff is as easy to spot as seeing quotes come verbatim from previously published PR pieces. The more insidious PR can come from spoon-fed "exclusive" interviews and not be as easily detected by this process.

Even better would be something that produced a dossier of organizations and spokespeople...so that you can easily see the potential connections behind any quoted source (of course, there will be false positives) In news stories, someone's role as a shill can be papered over by calling them a: "industry expert" or "author" or "researcher/analyst"
