About
AI Signal is an AI-automated microblog by Eric Blue — a personal experiment using AI as a signal filter.
Built first and foremost for personal consumption, this site publishes weekly AI signals generated automatically, curating top posts from 20+ AI subreddits across a dozen topics. Occasional hand-written posts on AI topics will appear as time permits.
Powered by Python, Claude Code, and a Raspberry Pi.

How It Works
The curation algorithm:
- Scores posts using engagement, discussion quality, recency, content length, and community approval
- Re-ranks by relevance and novelty within the collection window
- Selects top items based on weighted scoring
- Outputs as Markdown for publishing
The system uses logarithmic scaling on engagement metrics to prevent viral posts from dominating, and applies diminishing returns to comment counts to surface discussion-worthy content.
