This is extremely discouraging. I'm a little bit confused as to why this isn't getting more attention on HN.
Random chance. No one reads /newest, so it didn't get any upvotes when I posted it. Now a few days later it showed up on /r/machinelearning and people are trying to repost it and ending up here.
Yup, HN needs to work on allowing re-submissions. Sometimes the first submission of important issues don't get any attention because of random chance/bad titles/bad timing/etc.
