Update: we plan to officially start development on https://Remark.as early next year!
Are there any blog commenting systems made for different kinds of conversations? E.g. "I enjoyed this." vs. "Could you clarify?" vs. "Here's an essay on why you're wrong..."
I feel like all systems are just a variation on: "here's a text box, and here's everything anyone has entered into it in relation to this post." (Decentralized version only adds: "here's what people said elsewhere.")
