I found the Hartl RoR tutorial slow going, and couldn't parse whether my confusion was Rails, or Ruby, or REST concepts (& Rails implementation thereof), or TDD (which I found takes some getting used to). "Learning Rails" seems to involve learning some design practices and process tools that are less mandatory when learning other frameworks. But I'm just a newbie with some Python / Django familiarity, others may take to this stuff faster.

I have found those additions worthwhile. The work I've done in Django has gone a _lot_ faster, and I think better written, for the orientation to REST and TDD.

Perhaps real devs with more experience find these pieces less helpful and more intrusive?
