Huh. Apparently at least one journal out there has decided they won’t consider submissions unless there is the authors write a Wikipedia article too. I doubt that this is a satisfactory policy for math journals, but it’s good to see the desire for openness seeping in.
EDIT: Incidentally, to the smartasses thinking “wait, you can’t put original research on Wikipedia,” actually read the submission page. They recommend making the article on your userspace, and then porting it to the main Wikipedia after the paper is accepted. Yeesh, give the editors of RNA Biology a little credit.
