Depends, obviously. Some topics are asking for opinions on a design, a machine or notion, etc. So even if I suggest the same border design or machine as someone else, it has value to the OP that more than one person has the same suggestion. I think to say that one shouldn't respond at all unless they've read the entire thread is absurd. Now if I were posing a question, I'd read all the posts first to see if the answer was already given, but if another QB member fails to do that, big deal.
