How do we improve JavaScript usage, teach progressive enhancement and reconcile the community?
Super agree! There was a transition to get here and we have to transition away from it. We can't expect everybody to jump on board, especially when jumping on board means becoming an advocate for your whole team to have to relearn everything they know. We have to get real learning material out there (beyond just basic tutorials, like you say) and help these devs learn the patterns they need to transition their teams toward progressive enhancement.
