I registered and voted, and posted in the 'Defective screen' thread, which at least seems to be reasonably well-moderated against fanboy/girlism. (Although--and maybe I am being overly optimistic here--to my mind, now that Amazon is diverting some of the bad units to another location, I feel less need to make a lot of noise about it online. I think they've gotten the message. I hope. I'm completely addicted to reloading these forums now, though, and everytime someone gets a replacement I keep hoping to see the magical 'paper-white' screen.)
Edit: Oh god, my forum title is now Zealot. To anyone who still doubts there is a problem, in my apparently four years of membership here, I had exactly eight posts until I got my PW.
