MillionDollarPost
Post a message. Rank by spend.
What it does
Inspired by the old MillionDollarHomepage, this is a simple experiment in attention economics. Instead of likes or algorithms, visibility for posts is determined by spend. Each dollar buys one point, rankings decay over time, and anyone can overtake the leaderboard by paying more. Messages stay public, links are optional, and the constant decay keeps the leaderboard fun and dynamic.

- IBI built a message board where you pay to be the homepageMar 2026 · saythat.sh · ▲19
I kept thinking about what would happen if a message board only had one slot. One message, front and center, until someone pays to replace it. That's the entire product. You pay the current message's decayed value plus a penny to take the homepage. Message values drop over time using a gravity-based formula (same concept HN uses for ranking), so a $10 message might only cost a few bucks to replace a day later. Likes slow the decay, dislikes speed it up. The whole thing runs on three mini PCs in my house (k3s cluster, PostgreSQL, Redis Sentinel). Is it overengineered for a message board?…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
