Good question. There's filtering built in to keep noise down: reddit and hacker news posts need 50+ upvotes/points to make it through, and HN also has to match AI keywords. github only pulls the top 10 trending repos per language. arxiv and huggingface papers come through with less filtering since they're already curated by those communities.
there's also deduplication so the same link from multiple sources only shows once. the tradeoff is fewer posts but (hopefully) higher signal. I'm still working through happy to tune the thresholds if it feels too aggressive. The tradeoff is fewer posts but (hopefully) higher signal. User submissions bypass all that though, if you submit something it goes straight to the feed. So, I'm hoping folks find it useful enough to start sharing links they come across.
I'm still tweaking the approach for this, and the thresholds I picked are absolutely arbitrary, so I'm open to any feedback that can improve it!
