Trend Radar

Scans Hacker News for your topic over the last 1–30 days, merges relevance and recency results, and ranks every story by attention (points + weighted comments) and velocity (attention per hour). Then it writes a plain-English read of what the pattern means.

Why it matters

Hacker News is where technical early adopters decide what matters. Knowing which stories are rising — and which are argued about more than upvoted — tells you what to build, write about, or avoid.
