Serving the For You feed

Bluesky enables anyone to run a custom 'feed' implementation. spacecowboy's For You Feed serves ~72k users from a single Go process using SQLite on a gaming PC, storing 90 days of data (~419GB). Public traffic runs through a $7 OVH VPS via Tailscale; total cost is ~$30/month, and the system could scale to ~1M DAU with their cheapest algorithm.
