Show HN: I built a message board where you pay to be the homepage
The digital billboard where the only algorithm is capitalism. Post your message, or pay to replace the current one.

Original Text
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? Absolutely.
I genuinely don't know where this goes. Curious what HN thinks.
