DrNemesis...i actually find your findings to be a bit skewed.
while yes there are asshats, i find most of the people in LFD tool are capable of being either nice and informative or asshats. it depends on how YOU act also.
If i said "FFS slow down so i can drink" most of the time the person will ignore me or go faster.
If i said "can you please slow down a bit so i can keep up, im running OOM" most of the time the person slows down.
most of the time being more then 50% of course.
