I think it is interesting that with the diplomatic cable leaks we've seen more venom from those who were ambivalent, and more ambivalence from those who were supportive. (My own ambivalence increased with the release of the diplomatic gossip.) I think this speaks to a change of scale common in Web phenomena.
The technology of wiki (or the Web) changes the scale of what can be done -- be it to create a massive encyclopedia or dump massive leaks. The question for WikiLeaks is are they (1) simply a repository for information dumps -- in which case there is no redaction or discrimination -- or (2) a source of curated leaks?
If WikiLeaks is a information dump, it will be (rightfully) criticized for potentially harmful releases (to life, to diplomacy, to discretion). If curated, because WikiLeaks is not actually a wiki, I don't think it will be able to scale to the job, and will (inevitably?) be criticized for potentially harmful releases as well as incompetence/malice for doing a bad job.
For the future, what possible outcomes are we looking at? Will they attempt to define themselves as a dump, or otherwise, try to be more purposeful/discriminating? And even if WikiLeaks takes a more responsible/curated path, will there be others pursuing different paths now that the cat has been shown to be able to escape from the bag?
We discussed this issue at the Berkman Center today, part of which was recorded and will soon be available over at Media Berkman.
