Unfortunately, on the other hand you want them to be 'neutral' and 'credible'.
I believe Wikileaks does a good job of maintaining the middle ground by providing both raw documents and context and analysis. Your suggestion that they are generating conspiracies does not stand up to analysis: by providing raw documents they do the opposite.
With regards to immediacy, Wikileaks has explained their processes in the past with regards to source validation. One of the most obvious attacks against the organization would be publishing false information through them to discredit them publicly. Therefore all information received must be carefully researched and validated, as well as anonymized, before publication.
