I was doing it for a few weeks, but honestly I just happened to have the time then, and I don't now. I really wish that the news forum would be as full now as it was then, though. Here are the links to new sources that I'd gathered:

Primary sources are prefferable to secondary sources because:
A. We may get the story before someone else
B. No credit is due. "Siera announced" or such is completely sufficient
C. We may include interesting info that other sites don't

Secondary sources are good because:
A. Game devs do exclusives
B. You can find new primary sources this way.
C. Sometimes you skim over something important in a primary source
