I can't comment on the HN part of your comment, but I like the way you think, rms. People who design interactive web experiences do so under a lot of assumptions. Seems like you are always asking about the edge cases where the assumptions fall flat. What if I want to game the system to get as much karma as possible? What if I want to sell my karma -- it was my time I spent on the site, why shouldn't I own that effort I put in. Would it be any different than sitting side-by-side with another user and telling them how to work the site?
I have a feeling it ticks people off, but I like the questions. I think awesome business opportunities are built around folks who ask the same kind of askew questions that others don't consider. It's the lackeys following the main path of least resistance that have a harder time.
Good luck with your trip through the wilderness.
