Onchain Social isn’t about replacing platforms like X. It’s about building something that in principle can’t exist on X. What’s one thing Farcaster can enable that no Web2 platform ever could?

I'd say one thing Farcaster enables is composability, something no Web2 platform can replicate. Apps and protocols building on top of your profile, content, and interactions, rather than locking them in. Your followers, posts, and reputation move with you, instead of being trapped in a walled garden.

Real-World Example:
1. Warpcast (X-like) – You build your audience here.
2. New App Launches (e.g., Farcaster TikTok) – It instantly recognises your profile, followers, and reputation. You don’t need to rebuild from zero.
3. Developers Build Cool Features – "Top Farcaster creators", let you monetise all content, using the same base identity and data.

This wouldn’t be possible on X, because they own your data. Farcaster flips that, you own your network, and apps compete to serve you better.
