We don't typically search out and link up press releases, nor do we host court documents we obtain and the like. That's a far cry from being "horrible at referring" to sources. We link all non-PR sources otherwise.
Ben should have linked the Twitter account if he found the news from there, but they also sent out a full PR.
Caesar, I understand what you are saying, but you guys are pretty inconsistent about sources provided, especially in Opposable Thumbs. I am not asking you to host source material, just point to it and not just to other Ars articles (that is part of what makes it look bad, much less so when there is simply no links in the article). This article had no source, the "PSP Remaster" program has no sources (it is especially noticeable now that the YT video was yanked), and then the Oregon Trail and L.A. Noire articles have sources. The Xperia Play article only references other Ars articles, same with Gotham City Imposters.
It irks me more than anything else. And credit where credit it due: Sources are being provided far more often now. Especially with the science articles, I find them far more accessible. Thanks!
