I don't follow the forums super closely, but it definitely occurred to me that Amazon might have wanted to elicit the exact response that it did in the event that it viewed the forums as being dominated by trolling a-holes who might not be as willing to be a-holes if they knew light was shining on them. It seems like every time I drop in on a thread, there is always some group of people basically telling the original poster that Amazon isn't for them, their business model doesn't work on Amazon, they're stupid, or something of the sort. That's definitely one of the reasons why I rarely go there.
I made my last post here mostly because I found the idea of eliminating anonymity on an internet forum pretty funny. It's kind of like selling a car without the windshield...sure it will work, but it's going to be a whole less pleasant.
