How decentralized is Farcaster today?

Sign ups
- You can sign up permissionlessly with the smart contract as a developer
- You can sign up with Supercast, Herocast, Farquest (and maybe others...)

Data / APIs
- You can permissionlessly run a Hub
- There are thousands of independently run Hubs
- If you don't want to run a Hub, you can use an infra provider like Neynar or Airstack

Protocol vs. non-protocol features
- Casts, reactions, follows, profiles, verifications are all on Hubs
- Not on Hubs: channel metadata, settings and follows, direct casts, location in user profiles

If Warpcast labels me as spammy, is that censorship?
- Depends on your definition! If you have an existing audience — say 10K followers — then even if you get labeled spammy your existing your followers will see your content in feeds on Warpcast regardless of whether you use Warpcast or not..
- If you don't care about Warpcast (approximately 80% of signer activity), then your follow graph is already decentralized in the procol.

Apologies if there typos or grammatical mistakes. Written in a single 15 minute stream of conscious.
