Thanks for the feedback! It's actually creating its own database so as time goes on, it will show everything since it's been running. I didn't want to scrape through the backlog as I've already gotten banned a couple times while making this (prompting pg's recent unban post) and I didn't want to push my luck.

The upvotes thing is tricky because it's very time sensitive. I thought about it for a bit, but besides the difficulty in judging when to update the points, it also goes against the goal that all Show HNs are given the spotlight even if they didn't do so well.
