In some cases people refesh the page, see that theres a new question asked, click on it, read it, and reply to it. I've seen this donw with four people once, they all hit 'Submit' at the same time (not knowing theres someone else answering it) so you get a few answers saying the same thing, Also people have been know to clarify what previous people have stated above them, however these arn't the case for the thread you posted a link to. The only conclusion I can come to is people either A think there answer is explained more, or B just want a higher post count... :-k The mystery remains!
