nalgeon actually only submitted this once (24 hours ago), it got no traction and the other one (which did get traction) was submitted
after nalgeon's initial submission. This probably got into the second chance pool and ended up getting "resubmitted" (not an actual resubmission, a change in its submission time so it will have a chance to show up on the front page again).
