> Now I'm brainstorming how one might build a federated Reddit with public, signed mutation log, ala CT or other chains. And then multiple UIs could render the same public & federated data set.
Also the infrastructure which allows Reddit to exist is not. All those scaling issues they've "solved" over the past ten years? Have fun with those if you're trying to copy and paste the repo..
Reddit is 100% open source: https://github.com/reddit/reddit
