Can't blame you for thinking that way but sometimes when i read the threads question and the replies i too can't help but notice the similarities of answers, but i think it just shows that many people have the same opinions or either they're just copying the answers of the majority just to fit in. but that's just my opinion
I agree with you some time I also feel that there is something going wrong because when I see there are same question and answers are repeating by some people but in some place I see different question with different answers which is a good thing and that supposed to be like this because new question and new answer increased you knowledge so every day there must be something to learn and Im sure it will be continue forever.
