• David Humphrey: Thinking about Context

  I've written recently about my work on ChatCraft.org.  I've been doing a bunch of refactoring and new feature work, and things are in a pretty good state.  It mostly works the way I'd expect now.  Taras and Steven have filed a bunch of good ideas related to sharing, saving, and forking chats, and I've been exploring using SQLite Wasm for offline storage. But over the weekend I was thinking about something else.  Not a feature exactly, but a way of thinking about the linear flow of a chat.  The more I've worked with ChatCraft, the more I've learned about this form of dialog.  Because a number of separate features flow from this, I thought I'd start by sketching things out in my blog instead of git.
