Despite Dave Winer being an arsehole to me several times (I wear it as a badge of honour!), I have no qualm with saying he answers the question about Julian Assange's agenda pretty damn well (Does Assange Have An Agenda?).
Mr Assange and plenty of other people at Wikileaks and other sites are just doing what "news" organisations are supposed to be doing, instead of just being paid off, glorified subsidiaries of special interest groups, political parties and companies.
Those "news" organisations have been caught with their pants down, and they're understandably embarrassed and frustrated. Its harder for news to be curated and manufactured to fit a preferred narrative to condition readers and viewers when independent sources keep messing it up with facts.
