one of my big worries for sometime has been the "de-centralized" approach, while I understand leaving good managers alone to do their jobs, but I think it's easy for things to "slip" a bit over time. We, as humans, seem pre-programed for the ABC's of business decay (as Warren puts it). So, to be clear, de-central probably won't change in a big way, but I like Greg's "more active touch" with the subs. I think Greg's hardest job is keeping many of those long-time managers motivated to keep working without pissing on their grass.
