Farcaster

how would you describe farcaster to someone who primarily uses instagram or tiktok without saying it's like twitter

It’s an account that’s portable across all different social apps only you own it, not Facebook. People can build all kinds of different apps that connect to that account, from Twitter-style content feeds, to instagram-like photo/video experiences, Reddit-like forum experiences, video players, and even games. All of it, without having to pay Mark Zuckerberg or Elon Musk any money
