As part of the user feedback loop, we've found the PTL role extremely useful to channel feedback.  The operator PTL discussions during the Atlanta summit helped to clarify a number of areas where the PTL can then take the points back to the design summit. It is not clear how czars would address the outward facing part of the PTL role which is clearly needed in view of the various discussions around program management and priorities.

If we have lots of czars or major differences in how each project is structured, it is not clear how we channel user feedback to the project teams. Would there be a user czar on each project ?

I have no problem with lots of czars to delegate activities across the projects but having a single accountable and elected PTL who can choose the level of delegation (and be assessed on that) seems to be a very good feature.
