My point is that improvement does not grow out of negative feedback. This thread is about how the original post had just a torrent of negative and hostile feedback - that kind of feedback is not useful to the submitter for a whole host of reasons that SelfishMeme covered quite adeptly above.

There's a vast difference between honest feedback and what was in that thread. Publicly taking someone to task for a design experiment is shameful behavior, especially given this community's standards of participation.
