Did Kinja have a panic attack?

I do recall getting into a minor argument with agjios about the Mustang's numerous special editions in Caswell's Lime Rock M3 rant (damn near a year ago, wow), but what baffles me is how part of the conversation wound up in a completely unrelated io9 article. I think I've made one comment on Deadspin, but never on io9…

That when a post gets shared from another site (or personal blog) that was originally re-posted to oppo, but then gets shared to the front page, that the post on oppo disappears?

I just got a reply to a comment I made in October of 2010. I guess that's the Power of Kinja™. It was a tornado story, so somebody was probably looking through old threads in light of the news out of Oklahoma.

So did the editing feature go away, or am I not looking hard enough? Also, double-posting wouldn't be so bad if I could delete them.
