Who would read this? I skim Nature, Science, and some journals in my particular subfield every week/month because I am sure I will find something relevant to my research or generally interesting. With the exception of some hilarious or spectacular ones, I don't think Failures would be so engaging, so the only way I would find an article in Failures is if I specifically set out to search for it.
I might do that (though searching by technique is hard), but even if I found something, read it, and decided it was helpful, what would I do with it? For better or worse, citations are the currency of academia and academic publishing. Where would I cite a paper that specifically warned me away from a possible project? "Dear Nature, I was going to study XZY via ABC, but [1] indicates that's a dead end."
So, with no regular readers and no citations, Failures becomes more like a database than a journal. There currently aren't any good incentives to submit things to databases, so Failures becomes a....failure.
