I share your sentiment that a significant redesign could be a huge mistake. I think resisting the urge to redesign over the years has been huge for the growth of Reddit. And I think even a perfect redesign will be instinctually rejected by large swaths of the community (Markos Moulitsas used to say 1/3 of the community will hate a redesign no matter what it is.) In reddit's case the potential for rejection comes not just from typical human nature reasons but from specific cultural reasons particular to reddit: its propensity for hiveminding and collective freakouts, and consolidating around a narrative. They may be too big at this point to be undone by a redesign. But I hope the devs really, really know what they are doing.
