I started this as a project to learn Go, Backbone.js, Socket.io, and Redis. And thought that I may as well turn it into a tutorial in the hopes it helps other people learn too.<p>It's a live commenting system. Designed to be a cross between a chat-room and blog comments. It's pretty far from being done, but I felt that adding too many more features would make it a bit complex for a basic tutorial.<p>After I posted it I learned that actually, ending lines in Go with a semi-colon is discouraged, so, hind-sight is 20/20, and I may change that later to be more correct.<p>Hopefully people find it useful, and learn a bit.<p>Edit: Should mention, it's fairly basic, so there's no spam protection, or editing, or threads, yet... Eventually I'd like to include it on the page with my blog posts, but it's not quite ready for prime-time yet.
