This would be great. I'd love to have a place to go to check out the current state of the art. There's a huge amount to learn from other people's projects.
Additionally, votes cast there would be meaningful in terms of seeing which projects the community approves of - as opposed to on the front page, where the level of randomness in vote allocation is pretty huge.
People shouldn't have to wake up at 6am to post their cool weekend project for vote-optimization reasons if they just want some smart people's feedback.
So we have: Hacker News new | threads | comments | ask | jobs | submit
Why not just add a Show HN bit?
