What the OP wants is for people to speak up if they are unfamiliar or just new to the dungeon so that he can decide the best course of action. It's pretty true that newer players don't speak up when asked for fear of being looked down upon. However, there are a lot of players willing enough to take it step by step and help out when given the opportunity. Hence, what the OP is asking for is legitimate; speak up and he'll slow down. However, in this case, nobody spoke up until something probably bad happened.

Now you all are just arguing back and forth on whether or not speed runs are appropriate in DF with no conclusion and the complete disregard for the opinions of others when they disagree with you. Please get back on topic. No, I don't want to stroke your e-peens just because you think your opinion is the only absolute answer. This whole thing has already been argued with since the whole cutscene skipping fiasco - and we all know how that turned out. ಠ_ಠ
