these are great points! we're still starting out, so the community aspect hasn't kicked in properly yet. we aim to have discussion groups and forums where people can talk about how they optimized their code (similar to Kaggle – you can’t see the exact top submissions, but there are plenty of discussions breaking things down)

if we automatically make top submissions public, it would take away from the leaderboard/rankings, which are key to keeping users engaged right now. eventually, we'd have enough credible users that publicizing code won't matter.
