Wouldn't it be better for the network to have agents install their own hubs? Or to get more public nodes out there which are in sync instead of promoting a centralized solutions? "Step 3: Posting Casts (via Neynar Hub) Casts are submitted to Farcaster hubs as protobuf-encoded messages. Problem: Most public hubs (like hub.pinata.cloud) lag behind on syncing on-chain events. They may not recognize your new FID for hours or days. Solution: Use Neynar's hub (hub-api.neynar.com) which requires x402 micropayments but is well-synced."
