> Unlike Wikipedia, Nupedia was not a wiki; it was instead characterized by an extensive peer-review process, designed to make its articles of a quality comparable to that of professional encyclopedias. Nupedia wanted scholars (ideally with PhDs) to volunteer content.
I'm afraid that doesn't tell us the difference between Wikinews and WikiTribune.
I read your comment as "What's the difference to Wikinews", which is literally what you wrote, but you may have meant "with" which means my response was not directly relevant. WT ostensibly has made some changes/refinements -- which have tradeoffs that might be seen as undesirable to entrenched conventions at WN -- but it does seem that, on paper, WT and WN have the same fundamentals, i.e. what makes a Wiki what it is. And the content may not be substantively different either -- in fact, they could be mirrors of each other.
But my argument is that if WT's differences -- even if they are seemingly superficial like visual design and polish -- are enough to give WT even a veneer of authority and user-friendliness over WT, then the lack of fundamental differences is mostly besides the point. WT is a direct competitor to WN, few users are going to want to spend time/loyalty to both sites. And unlike Wikipedia, which has huge long-tail value, writing for a news site with a comparatively small audience would be a bit demoralizing when you could be writing for the much bigger competitor, especially if the pay (zero dollars) is exactly the same.
So the difference to WN is that if WT becomes more popular -- which it could just by Jimmy Wales continuing to be its salesman -- WN might become quickly lose its audience and purpose for existence.
