A few months ago, I decided to try a "gather impossible problems, hold off on proposing solutions until we've thoroughly understood them, then solve them" 'campaign'. The problems I came up with focused on blindness, so I started the discussion here rather than LW. I was surprised when I looked it up today and found that it only lasted for four days--I had been sure it had managed to drag on a little longer than that.
I recall someone tried something similar on LW, though considerably less focused and more willing to take things they couldn't be expected to solve without many more resources. I also recall that little if anything came of it.
Something tells me we're doing it wrong.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Of course, for "every Monday", the last one should have been dated July 22-28. *cough*
