I noticed that when changing from one chapter page to another, it loads much faster than the original rails tutorial, that takes forever. Nice improvement, still note a little latency though. It will be nice for people to study the Rails Tutorial Book when published on Softcover's new platform. Is going to happen?
There is already a version of the Rails Tutorial book that builds on Softcover, and in the coming weeks I plan to move the full tutorial over to the Softcover platform (taking care to preserve things like legacy download links). Watch for an announcement once the change-over is complete.
