the thing is: if people wish to discuss a puzzle I think it's up to them really. What should happen, in my opinion, is that people finish the puzzle and then come here to talk about it. But because lots of people come to the thread who HAVEN'T finished it, for whatever reason, then it becomes a problem, because hints may be gained which can help people to submit a solution. That is the bit which I think is wrong and disrespectful to the setter. (The solver has only himself to blame). And that's why (and I suspect you'd agree by the sound of it) really hints gained that may should dissuade people from sending in an entry.
Although these discussions are very interesting, and most people go to admirable lengths of self-restraint, proper discussion is impossible for that very reason. But I don't think we should be too hard these threads, as they've evolved from the typical "I'm stuck, give me a hint" approach to "I've finished it and I thought it was great/awful etc etc" which is good.
