The lack of any published high level security architecture for the WikiLeakS.org project
has been an ongoing failure, which reduces the level of trust and confidence which people can have in it.
Not all of the technical details of how they are trying to achieve the best mix of anonymity, security , scalability and usability techniques need to be made public, however a formal statement of what exactly they are trying to do, would help people outside the project to point out potential problems, or improvements, or to see that these have already been recognised and are work in progress.
In the absence of anything but the most hand waving salespeak from WikiLeakS.org, observers of the project have to critically examine the writings of their central politburo, and read between the lines,
The recently published Wikileaks:Investigator's guide page has some vaguely reassuring legal warnings about journalist / source legal protection in Sweden and Belgium and the USA.
This document is for judges, investigating magistrates, judicial officers and investigators. It explains issues and evidence that you may see in an investigation relating to Wikileaks.
This is not, therefore, a discussion document, soliciting ideas or feedback on proposed future project features, it appears to be a fait accompli.
However, the Investigator's Guide also contains some technical inaccuracies or, perhaps, deliberate misinformation, and a description of a very worrying "phone home" spyware "feature".
