Transparency in a wiki world

Despite being in PR for a long time and despite having a tech bent, I was unaware until today of wikileaks.org, a site that publishes anonymous submissions and leaks of sensitive governmental, corporate, or religious documents, while attempting to preserve the anonymity and untraceability of its contributors.

The site is a great reference site for journalists, particularly those chasing political stories but I can also see how it will be used by PR people wanting to place controlled leaks. I can only imagine that companies will start to use this site to place leaks about their own business or products, but also leaks about the actions of competitors. Of course in true wikipedia style they don't make it easy for people to place leaks on the site that will stick but equally, a factually correct leak should stay posted.
