Giving your anger a focal point can be productive, as it may inspire you to promote change.
Since IP lawsuits entered my field of awareness, starting with the Napster Trial, I've always wanted to set up a web site called "idancedonyourgrave.com" (or something with a similar sentiment). Morbid, but I want user-submitted pics of people actually dancing on the graves of people who have damaged our society through policy and abuse of the system.
My current candidates are: Lars Ulrich (Metallica, figurehead of the Napster lawsuit), Jack Valenti (former president of the MPAA -- hey, he's dead now, too!), Hillary Rosen (former president of the RIAA), and now I'll add Katherine Wolanyk (from the article, a co-founder of Soverain, patent troll).
