Well I think the consensus on the first two articles is pretty solid. I'll delete those later today, give someone time in case they have a reason to keep them (not bloody likely though).
But now we have a new situation that is definitely a lot less clear. The third article about the contest. Is this something that "belongs" on ProductWiki? What is the point of the News section anyway? This is especially important as both the News and Forum sections will be given more prominence in the near future (yes an update to the site is coming :D).
Thus far the idea has been pretty freeform. Pretty much any article is fair game as long as it's not total spam. Whether that's news about a company, or a product review, or thoughts about an industry, or even a rant about your bed. But maybe people want it to be a bit stricter and clear cut what should go there?
The forum will always be free-er in terms of content, so if the community decides it's better to be stricter on the "News" section then the other stuff can just go into forum discussions.
My personal thoughts are that we should keep it free form for now, and if we get more contest style articles we can re-examine the issue. But right now, it's just not that big of a deal.
